-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-# One issue with vendor `install' (even GNU) is that you can't

-# annoying in cross-compiling environments, where the build's strip
-# is unlikely to handle the host's binaries.
-# Fortunately install-sh will honor a STRIPPROG variable, so we
-# always use install-sh in `make install-strip', and initialize
-# STRIPPROG with the value of the STRIP variable (set by the user).

-# Installed binaries are usually stripped using `strip' when the user
-# run `make install-strip'.  However `strip' might not be the right
-# tool to use in cross-compilation environments, therefore Automake

-\`configure' configures dash 0.5.10.2 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]

-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-  YACC        The `Yet Another Compiler Compiler' implementation to use.
-              Defaults to the first program found out of: `bison -y', `byacc',
-              `yacc'.
-  YFLAGS      The list of arguments that will be passed by default to $YACC.
-              This script will default YFLAGS to the empty string to avoid a
-              default value of `-d' given by some make applications.
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

+#	@(#)TOUR	8.1 (Berkeley) 5/31/93
+
+NOTE -- This is the original TOUR paper distributed with ash and
+does not represent the current state of the shell.  It is provided anyway
+since it provides helpful information for how the shell is structured,
+but be warned that things have changed -- the current shell is
+still under development.
+
+================================================================
+
+                       A Tour through Ash
+
+               Copyright 1989 by Kenneth Almquist.
+
+
+DIRECTORIES:  The subdirectory bltin contains commands which can
+be compiled stand-alone.  The rest of the source is in the main
+ash directory.
+
+SOURCE CODE GENERATORS:  Files whose names begin with "mk" are
+programs that generate source code.  A complete list of these
+programs is:
+
+        program         intput files        generates
+        -------         ------------        ---------
+        mkbuiltins      builtins            builtins.h builtins.c
+        mkinit          *.c                 init.c
+        mknodes         nodetypes           nodes.h nodes.c
+        mksignames          -               signames.h signames.c
+        mksyntax            -               syntax.h syntax.c
+        mktokens            -               token.h
+        bltin/mkexpr    unary_op binary_op  operators.h operators.c
+
+There are undoubtedly too many of these.  Mkinit searches all the
+C source files for entries looking like:
+
+        INIT {
+              x = 1;    /* executed during initialization */
+        }
+
+        RESET {
+              x = 2;    /* executed when the shell does a longjmp
+                           back to the main command loop */
+        }
+
+It pulls this code out into routines which are when particular
+events occur.  The intent is to improve modularity by isolating
+the information about which modules need to be explicitly
+initialized/reset within the modules themselves.
+
+Mkinit recognizes several constructs for placing declarations in
+the init.c file.
+        INCLUDE "file.h"
+includes a file.  The storage class MKINIT makes a declaration
+available in the init.c file, for example:
+        MKINIT int funcnest;    /* depth of function calls */
+MKINIT alone on a line introduces a structure or union declara-
+tion:
+        MKINIT
+        struct redirtab {
+              short renamed[10];
+        };
+Preprocessor #define statements are copied to init.c without any
+special action to request this.
+
+INDENTATION:  The ash source is indented in multiples of six
+spaces.  The only study that I have heard of on the subject con-
+cluded that the optimal amount to indent is in the range of four
+to six spaces.  I use six spaces since it is not too big a jump
+from the widely used eight spaces.  If you really hate six space
+indentation, use the adjind (source included) program to change
+it to something else.
+
+EXCEPTIONS:  Code for dealing with exceptions appears in
+exceptions.c.  The C language doesn't include exception handling,
+so I implement it using setjmp and longjmp.  The global variable
+exception contains the type of exception.  EXERROR is raised by
+calling error.  EXINT is an interrupt.
+
+INTERRUPTS:  In an interactive shell, an interrupt will cause an
+EXINT exception to return to the main command loop.  (Exception:
+EXINT is not raised if the user traps interrupts using the trap
+command.)  The INTOFF and INTON macros (defined in exception.h)
+provide uninterruptable critical sections.  Between the execution
+of INTOFF and the execution of INTON, interrupt signals will be
+held for later delivery.  INTOFF and INTON can be nested.
+
+MEMALLOC.C:  Memalloc.c defines versions of malloc and realloc
+which call error when there is no memory left.  It also defines a
+stack oriented memory allocation scheme.  Allocating off a stack
+is probably more efficient than allocation using malloc, but the
+big advantage is that when an exception occurs all we have to do
+to free up the memory in use at the time of the exception is to
+restore the stack pointer.  The stack is implemented using a
+linked list of blocks.
+
+STPUTC:  If the stack were contiguous, it would be easy to store
+strings on the stack without knowing in advance how long the
+string was going to be:
+        p = stackptr;
+        *p++ = c;       /* repeated as many times as needed */
+        stackptr = p;
+The following three macros (defined in memalloc.h) perform these
+operations, but grow the stack if you run off the end:
+        STARTSTACKSTR(p);
+        STPUTC(c, p);   /* repeated as many times as needed */
+        grabstackstr(p);
+
+We now start a top-down look at the code:
+
+MAIN.C:  The main routine performs some initialization, executes
+the user's profile if necessary, and calls cmdloop.  Cmdloop is
+repeatedly parses and executes commands.
+
+OPTIONS.C:  This file contains the option processing code.  It is
+called from main to parse the shell arguments when the shell is
+invoked, and it also contains the set builtin.  The -i and -j op-
+tions (the latter turns on job control) require changes in signal
+handling.  The routines setjobctl (in jobs.c) and setinteractive
+(in trap.c) are called to handle changes to these options.
+
+PARSING:  The parser code is all in parser.c.  A recursive des-
+cent parser is used.  Syntax tables (generated by mksyntax) are
+used to classify characters during lexical analysis.  There are
+three tables:  one for normal use, one for use when inside single
+quotes, and one for use when inside double quotes.  The tables
+are machine dependent because they are indexed by character vari-
+ables and the range of a char varies from machine to machine.
+
+PARSE OUTPUT:  The output of the parser consists of a tree of
+nodes.  The various types of nodes are defined in the file node-
+types.
+
+Nodes of type NARG are used to represent both words and the con-
+tents of here documents.  An early version of ash kept the con-
+tents of here documents in temporary files, but keeping here do-
+cuments in memory typically results in significantly better per-
+formance.  It would have been nice to make it an option to use
+temporary files for here documents, for the benefit of small
+machines, but the code to keep track of when to delete the tem-
+porary files was complex and I never fixed all the bugs in it.
+(AT&T has been maintaining the Bourne shell for more than ten
+years, and to the best of my knowledge they still haven't gotten
+it to handle temporary files correctly in obscure cases.)
+
+The text field of a NARG structure points to the text of the
+word.  The text consists of ordinary characters and a number of
+special codes defined in parser.h.  The special codes are:
+
+        CTLVAR              Variable substitution
+        CTLENDVAR           End of variable substitution
+        CTLBACKQ            Command substitution
+        CTLESC              Escape next character
+
+A variable substitution contains the following elements:
+
+        CTLVAR type name '=' [ alternative-text CTLENDVAR ]
+
+The type field is a single character specifying the type of sub-
+stitution.  The possible types are:
+
+        VSNORMAL            $var
+        VSMINUS             ${var-text}
+        VSMINUS|VSNUL       ${var:-text}
+        VSPLUS              ${var+text}
+        VSPLUS|VSNUL        ${var:+text}
+        VSQUESTION          ${var?text}
+        VSQUESTION|VSNUL    ${var:?text}
+        VSASSIGN            ${var=text}
+        VSASSIGN|VSNUL      ${var=text}
+
+The name of the variable comes next, terminated by an equals
+sign.  If the type is not VSNORMAL, then the text field in the
+substitution follows, terminated by a CTLENDVAR byte.
+
+Commands in back quotes are parsed and stored in a linked list.
+The locations of these commands in the string are indicated by
+the CTLBACKQ character.
+
+The character CTLESC escapes the next character, so that in case
+any of the CTL characters mentioned above appear in the input,
+they can be passed through transparently.  CTLESC is also used to
+escape '*', '?', '[', and '!' characters which were quoted by the
+user and thus should not be used for file name generation.
+
+CTLESC characters have proved to be particularly tricky to get
+right.  In the case of here documents which are not subject to
+variable and command substitution, the parser doesn't insert any
+CTLESC characters to begin with (so the contents of the text
+field can be written without any processing).  Other here docu-
+ments, and words which are not subject to splitting and file name
+generation, have the CTLESC characters removed during the vari-
+able and command substitution phase.  Words which are subject
+splitting and file name generation have the CTLESC characters re-
+moved as part of the file name phase.
+
+EXECUTION:  Command execution is handled by the following files:
+        eval.c     The top level routines.
+        redir.c    Code to handle redirection of input and output.
+        jobs.c     Code to handle forking, waiting, and job control.
+        exec.c     Code to path searches and the actual exec sys call.
+        expand.c   Code to evaluate arguments.
+        var.c      Maintains the variable symbol table.  Called from expand.c.
+
+EVAL.C:  Evaltree recursively executes a parse tree.  The exit
+status is returned in the global variable exitstatus.  The alter-
+native entry evalbackcmd is called to evaluate commands in back
+quotes.  It saves the result in memory if the command is a buil-
+tin; otherwise it forks off a child to execute the command and
+connects the standard output of the child to a pipe.
+
+JOBS.C:  To create a process, you call makejob to return a job
+structure, and then call forkshell (passing the job structure as
+an argument) to create the process.  Waitforjob waits for a job
+to complete.  These routines take care of process groups if job
+control is defined.
+
+REDIR.C:  Ash allows file descriptors to be redirected and then
+restored without forking off a child process.  This is accom-
+plished by duplicating the original file descriptors.  The redir-
+tab structure records where the file descriptors have be dupli-
+cated to.
+
+EXEC.C:  The routine find_command locates a command, and enters
+the command in the hash table if it is not already there.  The
+third argument specifies whether it is to print an error message
+if the command is not found.  (When a pipeline is set up,
+find_command is called for all the commands in the pipeline be-
+fore any forking is done, so to get the commands into the hash
+table of the parent process.  But to make command hashing as
+transparent as possible, we silently ignore errors at that point
+and only print error messages if the command cannot be found
+later.)
+
+The routine shellexec is the interface to the exec system call.
+
+EXPAND.C:  Arguments are processed in three passes.  The first
+(performed by the routine argstr) performs variable and command
+substitution.  The second (ifsbreakup) performs word splitting
+and the third (expandmeta) performs file name generation.  If the
+"/u" directory is simulated, then when "/u/username" is replaced
+by the user's home directory, the flag "didudir" is set.  This
+tells the cd command that it should print out the directory name,
+just as it would if the "/u" directory were implemented using
+symbolic links.
+
+VAR.C:  Variables are stored in a hash table.  Probably we should
+switch to extensible hashing.  The variable name is stored in the
+same string as the value (using the format "name=value") so that
+no string copying is needed to create the environment of a com-
+mand.  Variables which the shell references internally are preal-
+located so that the shell can reference the values of these vari-
+ables without doing a lookup.
+
+When a program is run, the code in eval.c sticks any environment
+variables which precede the command (as in "PATH=xxx command") in
+the variable table as the simplest way to strip duplicates, and
+then calls "environment" to get the value of the environment.
+There are two consequences of this.  First, if an assignment to
+PATH precedes the command, the value of PATH before the assign-
+ment must be remembered and passed to shellexec.  Second, if the
+program turns out to be a shell procedure, the strings from the
+environment variables which preceded the command must be pulled
+out of the table and replaced with strings obtained from malloc,
+since the former will automatically be freed when the stack (see
+the entry on memalloc.c) is emptied.
+
+BUILTIN COMMANDS:  The procedures for handling these are scat-
+tered throughout the code, depending on which location appears
+most appropriate.  They can be recognized because their names al-
+ways end in "cmd".  The mapping from names to procedures is
+specified in the file builtins, which is processed by the mkbuil-
+tins command.
+
+A builtin command is invoked with argc and argv set up like a
+normal program.  A builtin command is allowed to overwrite its
+arguments.  Builtin routines can call nextopt to do option pars-
+ing.  This is kind of like getopt, but you don't pass argc and
+argv to it.  Builtin routines can also call error.  This routine
+normally terminates the shell (or returns to the main command
+loop if the shell is interactive), but when called from a builtin
+command it causes the builtin command to terminate with an exit
+status of 2.
+
+The directory bltins contains commands which can be compiled in-
+dependently but can also be built into the shell for efficiency
+reasons.  The makefile in this directory compiles these programs
+in the normal fashion (so that they can be run regardless of
+whether the invoker is ash), but also creates a library named
+bltinlib.a which can be linked with ash.  The header file bltin.h
+takes care of most of the differences between the ash and the
+stand-alone environment.  The user should call the main routine
+"main", and #define main to be the name of the routine to use
+when the program is linked into ash.  This #define should appear
+before bltin.h is included; bltin.h will #undef main if the pro-
+gram is to be compiled stand-alone.
+
+CD.C:  This file defines the cd and pwd builtins.  The pwd com-
+mand runs /bin/pwd the first time it is invoked (unless the user
+has already done a cd to an absolute pathname), but then
+remembers the current directory and updates it when the cd com-
+mand is run, so subsequent pwd commands run very fast.  The main
+complication in the cd command is in the docd command, which
+resolves symbolic links into actual names and informs the user
+where the user ended up if he crossed a symbolic link.
+
+SIGNALS:  Trap.c implements the trap command.  The routine set-
+signal figures out what action should be taken when a signal is
+received and invokes the signal system call to set the signal ac-
+tion appropriately.  When a signal that a user has set a trap for
+is caught, the routine "onsig" sets a flag.  The routine dotrap
+is called at appropriate points to actually handle the signal.
+When an interrupt is caught and no trap has been set for that
+signal, the routine "onint" in error.c is called.
+
+OUTPUT:  Ash uses it's own output routines.  There are three out-
+put structures allocated.  "Output" represents the standard out-
+put, "errout" the standard error, and "memout" contains output
+which is to be stored in memory.  This last is used when a buil-
+tin command appears in backquotes, to allow its output to be col-
+lected without doing any I/O through the UNIX operating system.
+The variables out1 and out2 normally point to output and errout,
+respectively, but they are set to point to memout when appropri-
+ate inside backquotes.
+
+INPUT:  The basic input routine is pgetc, which reads from the
+current input file.  There is a stack of input files; the current
+input file is the top file on this stack.  The code allows the
+input to come from a string rather than a file.  (This is for the
+-c option and the "." and eval builtin commands.)  The global
+variable plinno is saved and restored when files are pushed and
+popped from the stack.  The parser routines store the number of
+the current line in this variable.
+
+DEBUGGING:  If DEBUG is defined in shell.h, then the shell will
+write debugging information to the file $HOME/trace.  Most of
+this is done using the TRACE macro, which takes a set of printf
+arguments inside two sets of parenthesis.  Example:
+"TRACE(("n=%d0, n))".  The double parenthesis are necessary be-
+cause the preprocessor can't handle functions with a variable
+number of arguments.  Defining DEBUG also causes the shell to
+generate a core dump if it is sent a quit signal.  The tracing
+code is in show.c.

+.Ar args ...
+.Sh DESCRIPTION
+.Nm
+prints its arguments on the standard output, separated by spaces.
+Unless the
+.Fl n
+option is present, a newline is output following the arguments.
+The
+.Fl e
+option causes
+.Nm
+to treat the escape sequences specially, as described in the following
+paragraph.
+The
+.Fl e
+option is the default, and is provided solely for compatibility with
+other systems.
+Only one of the options
+.Fl n
+and
+.Fl e
+may be given.
+.Pp
+If any of the following sequences of characters is encountered during
+output, the sequence is not output.
+Instead, the specified action is
+performed:
+.Bl -tag -width indent
+.It Li \eb
+A backspace character is output.
+.It Li \ec
+Subsequent output is suppressed.
+This is normally used at the end of the
+last argument to suppress the trailing newline that
+.Nm
+would otherwise output.
+.It Li \ef
+Output a form feed.
+.It Li \en
+Output a newline character.
+.It Li \er
+Output a carriage return.
+.It Li \et
+Output a (horizontal) tab character.
+.It Li \ev
+Output a vertical tab.
+.It Li \e0 Ns Ar digits
+Output the character whose value is given by zero to three digits.
+If there are zero digits, a nul character is output.
+.It Li \e\e
+Output a backslash.
+.El
+.Sh HINTS
+Remember that backslash is special to the shell and needs to be escaped.
+To output a message to standard error, say
+.Pp
+.D1  echo message \*[Gt]\*[Am]2
+.Sh BUGS
+The octal character escape mechanism
+.Pq Li \e0 Ns Ar digits
+differs from the
+C language mechanism.
+.Pp
+There is no way to force
+.Nm
+to treat its arguments literally, rather than interpreting them as
+options and escape sequences.

+.Nd formatted output
+.Sh SYNOPSIS
+.Nm
+.Ar format
+.Op Ar arguments  ...
+.Sh DESCRIPTION
+.Nm
+formats and prints its arguments, after the first, under control
+of the
+.Ar format  .
+The
+.Ar format
+is a character string which contains three types of objects: plain characters,
+which are simply copied to standard output, character escape sequences which
+are converted and copied to the standard output, and format specifications,
+each of which causes printing of the next successive
+.Ar argument  .
+.Pp
+The
+.Ar arguments
+after the first are treated as strings if the corresponding format is
+either
+.Cm b ,
+.Cm B ,
+.Cm c
+or
+.Cm s ;
+otherwise it is evaluated as a C constant, with the following extensions:
+.Pp
+.Bl -bullet -offset indent -compact
+.It
+A leading plus or minus sign is allowed.
+.It
+If the leading character is a single or double quote, the value is the
+.Tn ASCII
+code of the next character.
+.El
+.Pp
+The format string is reused as often as necessary to satisfy the
+.Ar arguments  .
+Any extra format specifications are evaluated with zero or the null
+string.
+.Pp
+Character escape sequences are in backslash notation as defined in
+.St -ansiC .
+The characters and their meanings are as follows:
+.Bl -tag -width Ds -offset indent
+.It Cm \ee
+Write an \*[Lt]escape\*[Gt] character.
+.It Cm \ea
+Write a \*[Lt]bell\*[Gt] character.
+.It Cm \eb
+Write a \*[Lt]backspace\*[Gt] character.
+.It Cm \ef
+Write a \*[Lt]form-feed\*[Gt] character.
+.It Cm \en
+Write a \*[Lt]new-line\*[Gt] character.
+.It Cm \er
+Write a \*[Lt]carriage return\*[Gt] character.
+.It Cm \et
+Write a \*[Lt]tab\*[Gt] character.
+.It Cm \ev
+Write a \*[Lt]vertical tab\*[Gt] character.
+.It Cm \e\'
+Write a \*[Lt]single quote\*[Gt] character.
+.It Cm \e"
+Write a \*[Lt]double quote\*[Gt] character.
+.It Cm \e\e
+Write a backslash character.
+.It Cm \e Ns Ar num
+Write an 8\-bit character whose
+.Tn ASCII
+value is the 1\-, 2\-, or 3\-digit octal number
+.Ar num .
+.It Cm \ex Ns Ar xx
+Write an 8\-bit character whose
+.Tn ASCII
+value is the 1\- or 2\-digit hexadecimal number
+.Ar xx .
+.El
+.Pp
+Each format specification is introduced by the percent character
+(``%'').
+The remainder of the format specification includes,
+in the following order:
+.Bl -tag -width Ds
+.It "Zero or more of the following flags:"
+.Bl -tag -width Ds
+.It Cm #
+A `#' character
+specifying that the value should be printed in an ``alternative form''.
+For
+.Cm b ,
+.Cm c ,
+.Cm d ,
+and
+.Cm s
+formats, this option has no effect.
+For the
+.Cm o
+format the precision of the number is increased to force the first
+character of the output string to a zero.
+For the
+.Cm x
+.Pq Cm X
+format, a non-zero result has the string
+.Li 0x
+.Pq Li 0X
+prepended to it.
+For
+.Cm e  ,
+.Cm E ,
+.Cm f  ,
+.Cm g ,
+and
+.Cm G
+formats, the result will always contain a decimal point, even if no
+digits follow the point (normally, a decimal point only appears in the
+results of those formats if a digit follows the decimal point).
+For
+.Cm g
+and
+.Cm G
+formats, trailing zeros are not removed from the result as they
+would otherwise be.
+.\" I turned this off - decided it isn't a valid use of '#'
+.\" For the
+.\" .Cm B
+.\" format, backslash-escape sequences are expanded first;
+.It Cm \&\-
+A minus sign `\-' which specifies
+.Em left adjustment
+of the output in the indicated field;
+.It Cm \&+
+A `+' character specifying that there should always be
+a sign placed before the number when using signed formats.
+.It Sq \&\ \&
+A space specifying that a blank should be left before a positive number
+for a signed format.
+A `+' overrides a space if both are used;
+.It Cm \&0
+A zero `0' character indicating that zero-padding should be used
+rather than blank-padding.
+A `\-' overrides a `0' if both are used;
+.El
+.It "Field Width:"
+An optional digit string specifying a
+.Em field width ;
+if the output string has fewer characters than the field width it will
+be blank-padded on the left (or right, if the left-adjustment indicator
+has been given) to make up the field width (note that a leading zero
+is a flag, but an embedded zero is part of a field width);
+.It Precision :
+An optional period,
+.Sq Cm \&.\& ,
+followed by an optional digit string giving a
+.Em precision
+which specifies the number of digits to appear after the decimal point,
+for
+.Cm e
+and
+.Cm f
+formats, or the maximum number of characters to be printed
+from a string
+.Sm off
+.Pf ( Cm b Ns \&,
+.Sm on
+.Cm B
+and
+.Cm s
+formats); if the digit string is missing, the precision is treated
+as zero;
+.It Format :
+A character which indicates the type of format to use (one of
+.Cm diouxXfwEgGbBcs ) .
+.El
+.Pp
+A field width or precision may be
+.Sq Cm \&*
+instead of a digit string.
+In this case an
+.Ar argument
+supplies the field width or precision.
+.Pp
+The format characters and their meanings are:
+.Bl -tag -width Fl
+.It Cm diouXx
+The
+.Ar argument
+is printed as a signed decimal (d or i), unsigned octal, unsigned decimal,
+or unsigned hexadecimal (X or x), respectively.
+.It Cm f
+The
+.Ar argument
+is printed in the style
+.Sm off
+.Pf [\-]ddd Cm \&. No ddd
+.Sm on
+where the number of d's
+after the decimal point is equal to the precision specification for
+the argument.
+If the precision is missing, 6 digits are given; if the precision
+is explicitly 0, no digits and no decimal point are printed.
+.It Cm eE
+The
+.Ar argument
+is printed in the style
+.Sm off
+.Pf [\-]d Cm \&. No ddd Cm e No \\*(Pmdd
+.Sm on
+where there
+is one digit before the decimal point and the number after is equal to
+the precision specification for the argument; when the precision is
+missing, 6 digits are produced.
+An upper-case E is used for an `E' format.
+.It Cm gG
+The
+.Ar argument
+is printed in style
+.Cm f
+or in style
+.Cm e
+.Pq Cm E
+whichever gives full precision in minimum space.
+.It Cm b
+Characters from the string
+.Ar argument
+are printed with backslash-escape sequences expanded.
+.br
+The following additional backslash-escape sequences are supported:
+.Bl -tag -width Ds
+.It Cm \ec
+Causes
+.Nm
+to ignore any remaining characters in the string operand containing it,
+any remaining string operands, and any additional characters in
+the format operand.
+.It Cm \e0 Ns Ar num
+Write an 8\-bit character whose
+.Tn ASCII
+value is the 1\-, 2\-, or 3\-digit
+octal number
+.Ar num .
+.It Cm \e^ Ns Ar c
+Write the control character
+.Ar c .
+Generates characters `\e000' through `\e037`, and `\e177' (from `\e^?').
+.It Cm \eM\- Ns Ar c
+Write the character
+.Ar c
+with the 8th bit set.
+Generates characters `\e241' through `\e376`.
+.It Cm \eM^ Ns Ar c
+Write the control character
+.Ar c
+with the 8th bit set.
+Generates characters `\e000' through `\e037`, and `\e177' (from `\eM^?').
+.El
+.It Cm B
+Characters from the string
+.Ar argument
+are printed with unprintable characters backslash-escaped using the
+.Sm off
+.Pf ` Cm \e Ar c No ',
+.Pf ` Cm \e^ Ar c No ',
+.Pf ` Cm \eM\- Ar c No '
+or
+.Pf ` Cm \eM^ Ar c No ',
+.Sm on
+formats described above.
+.It Cm c
+The first character of
+.Ar argument
+is printed.
+.It Cm s
+Characters from the string
+.Ar argument
+are printed until the end is reached or until the number of characters
+indicated by the precision specification is reached; if the
+precision is omitted, all characters in the string are printed.
+.It Cm \&%
+Print a `%'; no argument is used.
+.El
+.Pp
+In no case does a non-existent or small field width cause truncation of
+a field; padding takes place only if the specified field width exceeds
+the actual width.
+.Sh EXIT STATUS
+.Nm
+exits 0 on success, 1 on failure.
+.Sh SEE ALSO
+.Xr echo 1 ,
+.Xr printf 3 ,
+.Xr printf 9 ,
+.Xr vis 3
+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -p1003.1-2001 .
+.Pp
+Support for the floating point formats and `*' as a field width and precision
+are optional in POSIX.
+.Pp
+The behaviour of the %B format and the \e', \e", \exxx, \ee and
+\e[M][\-|^]c escape sequences are undefined in POSIX.
+.Sh BUGS
+Since the floating point numbers are translated from
+.Tn ASCII
+to floating-point and
+then back again, floating-point precision may be lost.
+.Pp
+Hexadecimal character constants are restricted to, and should be specified
+as, two character constants.
+This is contrary to the ISO C standard but
+does guarantee detection of the end of the constant.

+.Sh DESCRIPTION
+The
+.Nm test
+utility evaluates the expression and, if it evaluates
+to true, returns a zero (true) exit status; otherwise
+it returns 1 (false).
+If there is no expression, test also
+returns 1 (false).
+.Pp
+All operators and flags are separate arguments to the
+.Nm test
+utility.
+.Pp
+The following primaries are used to construct expression:
+.Bl -tag -width Ar
+.It Fl b Ar file
+True if
+.Ar file
+exists and is a block special
+file.
+.It Fl c Ar file

+True if
+.Ar file
+exists and its set user ID flag
+is set.
+.It Fl w Ar file
+True if
+.Ar file
+exists and is writable.
+True
+indicates only that the write flag is on.
+The file is not writable on a read-only file
+system even if this test indicates true.
+.It Fl x Ar file
+True if
+.Ar file
+exists and is executable.
+True
+indicates only that the execute flag is on.
+If
+.Ar file
+is a directory, true indicates that
+.Ar file
+can be searched.
+.It Fl z Ar string
+True if the length of
+.Ar string
+is zero.
+.It Fl L Ar file
+True if
+.Ar file
+exists and is a symbolic link.
+This operator is retained for compatibility with previous versions of

+.It Ar \&s\&1 Cm \&\*[Gt] Ar \&s\&2
+True if string
+.Ar \&s\&1
+comes after

+or
+.Ar expression2
+are true.
+.It Cm \&( Ns Ar expression Ns Cm \&)
+True if expression is true.
+.El
+.Pp
+The
+.Fl a
+operator has higher precedence than the
+.Fl o
+operator.
+.Sh GRAMMAR AMBIGUITY
+The
+.Nm test
+grammar is inherently ambiguous.
+In order to assure a degree of consistency, the cases described in
+.St -p1003.2
+section 4.62.4,
+are evaluated consistently according to the rules specified in the
+standards document.
+All other cases are subject to the ambiguity in the command semantics.
+.Sh EXIT STATUS
+The
+.Nm test
+utility exits with one of the following values:
+.Bl -tag -width Ds
+.It 0
+expression evaluated to true.
+.It 1
+expression evaluated to false or expression was
+missing.
+.It \*[Gt]1
+An error occurred.
+.El
+.Sh STANDARDS
+The
+.Nm test
+utility implements a superset of the
+.St -p1003.2
+specification.

- * Similar to what access(2) does, but uses the effective uid and gid.
- * Doesn't make the mistake of telling root that any file is executable.
- * Returns non-zero if the file is accessible.
+ * The manual, and IEEE POSIX 1003.2, suggests this should check the mode bits,
+ * not use access():
+ *
+ *	True shall indicate only that the write flag is on.  The file is not
+ *	writable on a read-only file system even if this test indicates true.
+ *
+ * Unfortunately IEEE POSIX 1003.1-2001, as quoted in SuSv3, says only:
+ *
+ *	True shall indicate that permission to read from file will be granted,
+ *	as defined in "File Read, Write, and Creation".
+ *
+ * and that section says:
+ *
+ *	When a file is to be read or written, the file shall be opened with an
+ *	access mode corresponding to the operation to be performed.  If file
+ *	access permissions deny access, the requested operation shall fail.
+ *
+ * and of course access permissions are described as one might expect:
+ *
+ *     * If a process has the appropriate privilege:
+ *
+ *        * If read, write, or directory search permission is requested,
+ *          access shall be granted.
+ *
+ *        * If execute permission is requested, access shall be granted if
+ *          execute permission is granted to at least one user by the file
+ *          permission bits or by an alternate access control mechanism;
+ *          otherwise, access shall be denied.
+ *
+ *   * Otherwise:
+ *
+ *        * The file permission bits of a file contain read, write, and
+ *          execute/search permissions for the file owner class, file group
+ *          class, and file other class.
+ *
+ *        * Access shall be granted if an alternate access control mechanism
+ *          is not enabled and the requested access permission bit is set for
+ *          the class (file owner class, file group class, or file other class)
+ *          to which the process belongs, or if an alternate access control
+ *          mechanism is enabled and it allows the requested access; otherwise,
+ *          access shall be denied.
+ *
+ * and when I first read this I thought:  surely we can't go about using
+ * open(O_WRONLY) to try this test!  However the POSIX 1003.1-2001 Rationale
+ * section for test does in fact say:
+ *
+ *	On historical BSD systems, test -w directory always returned false
+ *	because test tried to open the directory for writing, which always
+ *	fails.
+ *
+ * and indeed this is in fact true for Seventh Edition UNIX, UNIX 32V, and UNIX
+ * System III, and thus presumably also for BSD up to and including 4.3.
+ *
+ * Secondly I remembered why using open() and/or access() are bogus.  They
+ * don't work right for detecting read and write permissions bits when called
+ * by root.
+ *
+ * Interestingly the 'test' in 4.4BSD was closer to correct (as per
+ * 1003.2-1992) and it was implemented efficiently with stat() instead of
+ * open().
+ *
+ * This was apparently broken in NetBSD around about 1994/06/30 when the old
+ * 4.4BSD implementation was replaced with a (arguably much better coded)
+ * implementation derived from pdksh.
+ *
+ * Note that modern pdksh is yet different again, but still not correct, at
+ * least not w.r.t. 1003.2-1992.
+ *
+ * As I think more about it and read more of the related IEEE docs I don't like
+ * that wording about 'test -r' and 'test -w' in 1003.1-2001 at all.  I very
+ * much prefer the original wording in 1003.2-1992.  It is much more useful,
+ * and so that's what I've implemented.
+ *
+ * (Note that a strictly conforming implementation of 1003.1-2001 is in fact
+ * totally useless for the case in question since its 'test -w' and 'test -r'
+ * can never fail for root for any existing files, i.e. files for which 'test
+ * -e' succeeds.)
+ *
+ * The rationale for 1003.1-2001 suggests that the wording was "clarified" in
+ * 1003.1-2001 to align with the 1003.2b draft.  1003.2b Draft 12 (July 1999),
+ * which is the latest copy I have, does carry the same suggested wording as is
+ * in 1003.1-2001, with its rationale saying:
+ *
+ * 	This change is a clarification and is the result of interpretation
+ * 	request PASC 1003.2-92 #23 submitted for IEEE Std 1003.2-1992.
+ *
+ * That interpretation can be found here:
+ *
+ *   http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-23.html
+ *
+ * Not terribly helpful, unfortunately.  I wonder who that fence sitter was.
+ *
+ * Worse, IMVNSHO, I think the authors of 1003.2b-D12 have mis-interpreted the
+ * PASC interpretation and appear to be gone against at least one widely used
+ * implementation (namely 4.4BSD).  The problem is that for file access by root
+ * this means that if test '-r' and '-w' are to behave as if open() were called
+ * then there's no way for a shell script running as root to check if a file
+ * has certain access bits set other than by the grotty means of interpreting
+ * the output of 'ls -l'.  This was widely considered to be a bug in V7's
+ * "test" and is, I believe, one of the reasons why direct use of access() was
+ * avoided in some more recent implementations!
+ *
+ * I have always interpreted '-r' to match '-w' and '-x' as per the original
+ * wording in 1003.2-1992, not the other way around.  I think 1003.2b goes much
+ * too far the wrong way without any valid rationale and that it's best if we
+ * stick with 1003.2-1992 and test the flags, and not mimic the behaviour of
+ * open() since we already know very well how it will work -- existance of the
+ * file is all that matters to open() for root.
+ *
+ * Unfortunately the SVID is no help at all (which is, I guess, partly why
+ * we're in this mess in the first place :-).
+ *
+ * The SysV implementation (at least in the 'test' builtin in /bin/sh) does use
+ * access(name, 2) even though it also goes to much greater lengths for '-x'
+ * matching the 1003.2-1992 definition (which is no doubt where that definition
+ * came from).
+ *
+ * The ksh93 implementation uses access() for '-r' and '-w' if
+ * (euid==uid&&egid==gid), but uses st_mode for '-x' iff running as root.
+ * i.e. it does strictly conform to 1003.1-2001 (and presumably 1003.2b).

  *
- * System V doesn't have a non-blocking wait system call.  It does
- * have a SIGCLD signal that is sent to a process when one of it's
- * children dies.  The obvious way to use SIGCLD would be to install
- * a handler for SIGCLD which simply bumped a counter when a SIGCLD
- * was received, and have waitproc bump another counter when it got
- * the status of a process.  Waitproc would then know that a wait
- * system call would not block if the two counters were different.
- * This approach doesn't work because if a process has children that
- * have not been waited for, System V will send it a SIGCLD when it
- * installs a signal handler for SIGCLD.  What this means is that when
- * a child exits, the shell will be sent SIGCLD signals continuously
- * until is runs out of stack space, unless it does a wait call before
- * restoring the signal handler.  The code below takes advantage of
- * this (mis)feature by installing a signal handler for SIGCLD and
- * then checking to see whether it was called.  If there are any
- * children to be waited for, it will be.
+ * We use sigsuspend in conjunction with a non-blocking wait3 in
+ * order to ensure that waitcmd exits promptly upon the reception
+ * of a signal.
  *
- * If neither SYSV nor BSD is defined, we don't implement nonblocking
- * waits at all.  In this case, the user will not be informed when
- * a background process until the next time she runs a real program
- * (as opposed to running a builtin command or just typing return),
- * and the jobs command may give out of date information.
+ * For code paths other than waitcmd we either use a blocking wait3

+
+Basic Installation
+==================
+
+   Briefly, the shell command './configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the 'README' file for
+instructions specific to this package.  Some packages provide this
+'INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package.
+It may also create one or more '.h' files containing system-dependent
+definitions.  Finally, it creates a shell script 'config.status' that
+you can run in the future to recreate the current configuration, and a
+file 'config.log' containing compiler output (useful mainly for
+debugging 'configure').
+
+   It can also use an optional file (typically called 'config.cache' and
+enabled with '--cache-file=config.cache' or simply '-C') that saves the
+results of its tests to speed up reconfiguring.  Caching is disabled by
+default to prevent problems with accidental use of stale cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how 'configure' could check whether to do them, and mail
+diffs or instructions to the address given in the 'README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point 'config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file 'configure.ac' (or 'configure.in') is used to create
+'configure' by a program called 'autoconf'.  You need 'configure.ac' if
+you want to change it or regenerate 'configure' using a newer version of
+'autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. 'cd' to the directory containing the package's source code and type
+     './configure' to configure the package for your system.
+
+     Running 'configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type 'make' to compile the package.
+
+  3. Optionally, type 'make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type 'make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the 'make install' phase executed with root
+     privileges.
+
+  5. Optionally, type 'make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior 'make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing 'make clean'.  To also remove the
+     files that 'configure' created (so you can compile the package for
+     a different kind of computer), type 'make distclean'.  There is
+     also a 'make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type 'make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide 'make
+     distcheck', which can by used by developers to test that all other
+     targets like 'make install' and 'make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the 'configure' script does not know about.  Run './configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give 'configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here is
+an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU 'make'.  'cd' to the
+directory where you want the object files and executables to go and run
+the 'configure' script.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.  This is known
+as a "VPATH" build.
+
+   With a non-GNU 'make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use 'make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple '-arch' options to the
+compiler but only a single '-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the 'lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, 'make install' installs the package's commands under
+'/usr/local/bin', include files under '/usr/local/include', etc.  You
+can specify an installation prefix other than '/usr/local' by giving
+'configure' the option '--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like '--bindir=DIR' to specify different values for particular
+kinds of files.  Run 'configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the default
+for these options is expressed in terms of '${prefix}', so that
+specifying just '--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to 'configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+'make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, 'make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+'${prefix}'.  Any directories that were specified during 'configure',
+but not in terms of '${prefix}', must each be overridden at install time
+for the entire installation to be relocated.  The approach of makefile
+variable overrides for each directory variable is required by the GNU
+Coding Standards, and ideally causes no recompilation.  However, some
+platforms have known limitations with the semantics of shared libraries
+that end up requiring recompilation when using this method, particularly
+noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the 'DESTDIR' variable.  For
+example, 'make install DESTDIR=/alternate/directory' will prepend
+'/alternate/directory' before all installation names.  The approach of
+'DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of '${prefix}'
+at 'configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving 'configure' the
+option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
+
+   Some packages pay attention to '--enable-FEATURE' options to
+'configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to '--with-PACKAGE' options, where PACKAGE
+is something like 'gnu-as' or 'x' (for the X Window System).  The
+'README' should mention any '--enable-' and '--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, 'configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the 'configure' options '--x-includes=DIR' and
+'--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of 'make' will be.  For these packages, running './configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with 'make V=1'; while running './configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with 'make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
+is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX 'make' updates targets which have the same time stamps as their
+prerequisites, which makes it generally unusable when shipped generated
+files such as 'configure' are involved.  Use GNU 'make' instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
+workaround.  If GNU CC is not installed, it is therefore recommended to
+try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
+in your 'PATH', put it _after_ '/usr/bin'.
+
+   On Haiku, software installed for all users goes in '/boot/common',
+not '/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features 'configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, 'configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+'--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as 'sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file 'config.sub' for the possible values of each field.  If
+'config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option '--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with '--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for 'configure' scripts to share,
+you can create a site shell script called 'config.site' that gives
+default values for variables like 'CC', 'cache_file', and 'prefix'.
+'configure' looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all 'configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to 'configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the 'configure' command line, using 'VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified 'gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
+Autoconf limitation.  Until the limitation is lifted, you can use this
+workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+'configure' Invocation
+======================
+
+   'configure' recognizes the following options to control how it
+operates.
+
+'--help'
+'-h'
+     Print a summary of all of the options to 'configure', and exit.
+
+'--help=short'
+'--help=recursive'
+     Print a summary of the options unique to this package's
+     'configure', and exit.  The 'short' variant lists options used only
+     in the top level, while the 'recursive' variant lists options also
+     present in any nested packages.
+
+'--version'
+'-V'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+'--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally 'config.cache'.  FILE defaults to '/dev/null' to
+     disable caching.
+
+'--config-cache'
+'-C'
+     Alias for '--cache-file=config.cache'.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to '/dev/null' (any error
+     messages will still be shown).
+
+'--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+
+'--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names:: for
+     more details, including other options available for fine-tuning the
+     installation locations.
+
+'--no-create'
+'-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+'configure' also accepts some other, not widely useful, options.  Run
+'configure --help' for more details.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures dash 0.5.12 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

-#	@(#)TOUR	8.1 (Berkeley) 5/31/93
-
-NOTE -- This is the original TOUR paper distributed with ash and
-does not represent the current state of the shell.  It is provided anyway
-since it provides helpful information for how the shell is structured,
-but be warned that things have changed -- the current shell is
-still under development.
-
-================================================================
-
-                       A Tour through Ash
-
-               Copyright 1989 by Kenneth Almquist.
-
-
-DIRECTORIES:  The subdirectory bltin contains commands which can
-be compiled stand-alone.  The rest of the source is in the main
-ash directory.
-
-SOURCE CODE GENERATORS:  Files whose names begin with "mk" are
-programs that generate source code.  A complete list of these
-programs is:
-
-        program         intput files        generates
-        -------         ------------        ---------
-        mkbuiltins      builtins            builtins.h builtins.c
-        mkinit          *.c                 init.c
-        mknodes         nodetypes           nodes.h nodes.c
-        mksignames          -               signames.h signames.c
-        mksyntax            -               syntax.h syntax.c
-        mktokens            -               token.h
-        bltin/mkexpr    unary_op binary_op  operators.h operators.c
-
-There are undoubtedly too many of these.  Mkinit searches all the
-C source files for entries looking like:
-
-        INIT {
-              x = 1;    /* executed during initialization */
-        }
-
-        RESET {
-              x = 2;    /* executed when the shell does a longjmp
-                           back to the main command loop */
-        }
-
-It pulls this code out into routines which are when particular
-events occur.  The intent is to improve modularity by isolating
-the information about which modules need to be explicitly
-initialized/reset within the modules themselves.
-
-Mkinit recognizes several constructs for placing declarations in
-the init.c file.
-        INCLUDE "file.h"
-includes a file.  The storage class MKINIT makes a declaration
-available in the init.c file, for example:
-        MKINIT int funcnest;    /* depth of function calls */
-MKINIT alone on a line introduces a structure or union declara-
-tion:
-        MKINIT
-        struct redirtab {
-              short renamed[10];
-        };
-Preprocessor #define statements are copied to init.c without any
-special action to request this.
-
-INDENTATION:  The ash source is indented in multiples of six
-spaces.  The only study that I have heard of on the subject con-
-cluded that the optimal amount to indent is in the range of four
-to six spaces.  I use six spaces since it is not too big a jump
-from the widely used eight spaces.  If you really hate six space
-indentation, use the adjind (source included) program to change
-it to something else.
-
-EXCEPTIONS:  Code for dealing with exceptions appears in
-exceptions.c.  The C language doesn't include exception handling,
-so I implement it using setjmp and longjmp.  The global variable
-exception contains the type of exception.  EXERROR is raised by
-calling error.  EXINT is an interrupt.
-
-INTERRUPTS:  In an interactive shell, an interrupt will cause an
-EXINT exception to return to the main command loop.  (Exception:
-EXINT is not raised if the user traps interrupts using the trap
-command.)  The INTOFF and INTON macros (defined in exception.h)
-provide uninterruptable critical sections.  Between the execution
-of INTOFF and the execution of INTON, interrupt signals will be
-held for later delivery.  INTOFF and INTON can be nested.
-
-MEMALLOC.C:  Memalloc.c defines versions of malloc and realloc
-which call error when there is no memory left.  It also defines a
-stack oriented memory allocation scheme.  Allocating off a stack
-is probably more efficient than allocation using malloc, but the
-big advantage is that when an exception occurs all we have to do
-to free up the memory in use at the time of the exception is to
-restore the stack pointer.  The stack is implemented using a
-linked list of blocks.
-
-STPUTC:  If the stack were contiguous, it would be easy to store
-strings on the stack without knowing in advance how long the
-string was going to be:
-        p = stackptr;
-        *p++ = c;       /* repeated as many times as needed */
-        stackptr = p;
-The following three macros (defined in memalloc.h) perform these
-operations, but grow the stack if you run off the end:
-        STARTSTACKSTR(p);
-        STPUTC(c, p);   /* repeated as many times as needed */
-        grabstackstr(p);
-
-We now start a top-down look at the code:
-
-MAIN.C:  The main routine performs some initialization, executes
-the user's profile if necessary, and calls cmdloop.  Cmdloop is
-repeatedly parses and executes commands.
-
-OPTIONS.C:  This file contains the option processing code.  It is
-called from main to parse the shell arguments when the shell is
-invoked, and it also contains the set builtin.  The -i and -j op-
-tions (the latter turns on job control) require changes in signal
-handling.  The routines setjobctl (in jobs.c) and setinteractive
-(in trap.c) are called to handle changes to these options.
-
-PARSING:  The parser code is all in parser.c.  A recursive des-
-cent parser is used.  Syntax tables (generated by mksyntax) are
-used to classify characters during lexical analysis.  There are
-three tables:  one for normal use, one for use when inside single
-quotes, and one for use when inside double quotes.  The tables
-are machine dependent because they are indexed by character vari-
-ables and the range of a char varies from machine to machine.
-
-PARSE OUTPUT:  The output of the parser consists of a tree of
-nodes.  The various types of nodes are defined in the file node-
-types.
-
-Nodes of type NARG are used to represent both words and the con-
-tents of here documents.  An early version of ash kept the con-
-tents of here documents in temporary files, but keeping here do-
-cuments in memory typically results in significantly better per-
-formance.  It would have been nice to make it an option to use
-temporary files for here documents, for the benefit of small
-machines, but the code to keep track of when to delete the tem-
-porary files was complex and I never fixed all the bugs in it.
-(AT&T has been maintaining the Bourne shell for more than ten
-years, and to the best of my knowledge they still haven't gotten
-it to handle temporary files correctly in obscure cases.)
-
-The text field of a NARG structure points to the text of the
-word.  The text consists of ordinary characters and a number of
-special codes defined in parser.h.  The special codes are:
-
-        CTLVAR              Variable substitution
-        CTLENDVAR           End of variable substitution
-        CTLBACKQ            Command substitution
-        CTLESC              Escape next character
-
-A variable substitution contains the following elements:
-
-        CTLVAR type name '=' [ alternative-text CTLENDVAR ]
-
-The type field is a single character specifying the type of sub-
-stitution.  The possible types are:
-
-        VSNORMAL            $var
-        VSMINUS             ${var-text}
-        VSMINUS|VSNUL       ${var:-text}
-        VSPLUS              ${var+text}
-        VSPLUS|VSNUL        ${var:+text}
-        VSQUESTION          ${var?text}
-        VSQUESTION|VSNUL    ${var:?text}
-        VSASSIGN            ${var=text}
-        VSASSIGN|VSNUL      ${var=text}
-
-The name of the variable comes next, terminated by an equals
-sign.  If the type is not VSNORMAL, then the text field in the
-substitution follows, terminated by a CTLENDVAR byte.
-
-Commands in back quotes are parsed and stored in a linked list.
-The locations of these commands in the string are indicated by
-the CTLBACKQ character.
-
-The character CTLESC escapes the next character, so that in case
-any of the CTL characters mentioned above appear in the input,
-they can be passed through transparently.  CTLESC is also used to
-escape '*', '?', '[', and '!' characters which were quoted by the
-user and thus should not be used for file name generation.
-
-CTLESC characters have proved to be particularly tricky to get
-right.  In the case of here documents which are not subject to
-variable and command substitution, the parser doesn't insert any
-CTLESC characters to begin with (so the contents of the text
-field can be written without any processing).  Other here docu-
-ments, and words which are not subject to splitting and file name
-generation, have the CTLESC characters removed during the vari-
-able and command substitution phase.  Words which are subject
-splitting and file name generation have the CTLESC characters re-
-moved as part of the file name phase.
-
-EXECUTION:  Command execution is handled by the following files:
-        eval.c     The top level routines.
-        redir.c    Code to handle redirection of input and output.
-        jobs.c     Code to handle forking, waiting, and job control.
-        exec.c     Code to path searches and the actual exec sys call.
-        expand.c   Code to evaluate arguments.
-        var.c      Maintains the variable symbol table.  Called from expand.c.
-
-EVAL.C:  Evaltree recursively executes a parse tree.  The exit
-status is returned in the global variable exitstatus.  The alter-
-native entry evalbackcmd is called to evaluate commands in back
-quotes.  It saves the result in memory if the command is a buil-
-tin; otherwise it forks off a child to execute the command and
-connects the standard output of the child to a pipe.
-
-JOBS.C:  To create a process, you call makejob to return a job
-structure, and then call forkshell (passing the job structure as
-an argument) to create the process.  Waitforjob waits for a job
-to complete.  These routines take care of process groups if job
-control is defined.
-
-REDIR.C:  Ash allows file descriptors to be redirected and then
-restored without forking off a child process.  This is accom-
-plished by duplicating the original file descriptors.  The redir-
-tab structure records where the file descriptors have be dupli-
-cated to.
-
-EXEC.C:  The routine find_command locates a command, and enters
-the command in the hash table if it is not already there.  The
-third argument specifies whether it is to print an error message
-if the command is not found.  (When a pipeline is set up,
-find_command is called for all the commands in the pipeline be-
-fore any forking is done, so to get the commands into the hash
-table of the parent process.  But to make command hashing as
-transparent as possible, we silently ignore errors at that point
-and only print error messages if the command cannot be found
-later.)
-
-The routine shellexec is the interface to the exec system call.
-
-EXPAND.C:  Arguments are processed in three passes.  The first
-(performed by the routine argstr) performs variable and command
-substitution.  The second (ifsbreakup) performs word splitting
-and the third (expandmeta) performs file name generation.  If the
-"/u" directory is simulated, then when "/u/username" is replaced
-by the user's home directory, the flag "didudir" is set.  This
-tells the cd command that it should print out the directory name,
-just as it would if the "/u" directory were implemented using
-symbolic links.
-
-VAR.C:  Variables are stored in a hash table.  Probably we should
-switch to extensible hashing.  The variable name is stored in the
-same string as the value (using the format "name=value") so that
-no string copying is needed to create the environment of a com-
-mand.  Variables which the shell references internally are preal-
-located so that the shell can reference the values of these vari-
-ables without doing a lookup.
-
-When a program is run, the code in eval.c sticks any environment
-variables which precede the command (as in "PATH=xxx command") in
-the variable table as the simplest way to strip duplicates, and
-then calls "environment" to get the value of the environment.
-There are two consequences of this.  First, if an assignment to
-PATH precedes the command, the value of PATH before the assign-
-ment must be remembered and passed to shellexec.  Second, if the
-program turns out to be a shell procedure, the strings from the
-environment variables which preceded the command must be pulled
-out of the table and replaced with strings obtained from malloc,
-since the former will automatically be freed when the stack (see
-the entry on memalloc.c) is emptied.
-
-BUILTIN COMMANDS:  The procedures for handling these are scat-
-tered throughout the code, depending on which location appears
-most appropriate.  They can be recognized because their names al-
-ways end in "cmd".  The mapping from names to procedures is
-specified in the file builtins, which is processed by the mkbuil-
-tins command.
-
-A builtin command is invoked with argc and argv set up like a
-normal program.  A builtin command is allowed to overwrite its
-arguments.  Builtin routines can call nextopt to do option pars-
-ing.  This is kind of like getopt, but you don't pass argc and
-argv to it.  Builtin routines can also call error.  This routine
-normally terminates the shell (or returns to the main command
-loop if the shell is interactive), but when called from a builtin
-command it causes the builtin command to terminate with an exit
-status of 2.
-
-The directory bltins contains commands which can be compiled in-
-dependently but can also be built into the shell for efficiency
-reasons.  The makefile in this directory compiles these programs
-in the normal fashion (so that they can be run regardless of
-whether the invoker is ash), but also creates a library named
-bltinlib.a which can be linked with ash.  The header file bltin.h
-takes care of most of the differences between the ash and the
-stand-alone environment.  The user should call the main routine
-"main", and #define main to be the name of the routine to use
-when the program is linked into ash.  This #define should appear
-before bltin.h is included; bltin.h will #undef main if the pro-
-gram is to be compiled stand-alone.
-
-CD.C:  This file defines the cd and pwd builtins.  The pwd com-
-mand runs /bin/pwd the first time it is invoked (unless the user
-has already done a cd to an absolute pathname), but then
-remembers the current directory and updates it when the cd com-
-mand is run, so subsequent pwd commands run very fast.  The main
-complication in the cd command is in the docd command, which
-resolves symbolic links into actual names and informs the user
-where the user ended up if he crossed a symbolic link.
-
-SIGNALS:  Trap.c implements the trap command.  The routine set-
-signal figures out what action should be taken when a signal is
-received and invokes the signal system call to set the signal ac-
-tion appropriately.  When a signal that a user has set a trap for
-is caught, the routine "onsig" sets a flag.  The routine dotrap
-is called at appropriate points to actually handle the signal.
-When an interrupt is caught and no trap has been set for that
-signal, the routine "onint" in error.c is called.
-
-OUTPUT:  Ash uses it's own output routines.  There are three out-
-put structures allocated.  "Output" represents the standard out-
-put, "errout" the standard error, and "memout" contains output
-which is to be stored in memory.  This last is used when a buil-
-tin command appears in backquotes, to allow its output to be col-
-lected without doing any I/O through the UNIX operating system.
-The variables out1 and out2 normally point to output and errout,
-respectively, but they are set to point to memout when appropri-
-ate inside backquotes.
-
-INPUT:  The basic input routine is pgetc, which reads from the
-current input file.  There is a stack of input files; the current
-input file is the top file on this stack.  The code allows the
-input to come from a string rather than a file.  (This is for the
--c option and the "." and eval builtin commands.)  The global
-variable plinno is saved and restored when files are pushed and
-popped from the stack.  The parser routines store the number of
-the current line in this variable.
-
-DEBUGGING:  If DEBUG is defined in shell.h, then the shell will
-write debugging information to the file $HOME/trace.  Most of
-this is done using the TRACE macro, which takes a set of printf
-arguments inside two sets of parenthesis.  Example:
-"TRACE(("n=%d0, n))".  The double parenthesis are necessary be-
-cause the preprocessor can't handle functions with a variable
-number of arguments.  Defining DEBUG also causes the shell to
-generate a core dump if it is sent a quit signal.  The tracing
-code is in show.c.

-.Sh NAME
-.Nm printf
-.Nd formatted output
-.Sh SYNOPSIS
-.Nm
-.Ar format
-.Op Ar arguments  ...
-.Sh DESCRIPTION
-.Nm
-formats and prints its arguments, after the first, under control
-of the
-.Ar format  .
-The
-.Ar format
-is a character string which contains three types of objects: plain characters,
-which are simply copied to standard output, character escape sequences which
-are converted and copied to the standard output, and format specifications,
-each of which causes printing of the next successive
-.Ar argument  .
-.Pp
-The
-.Ar arguments
-after the first are treated as strings if the corresponding format is
-either
-.Cm b ,
-.Cm B ,
-.Cm c
-or
-.Cm s ;
-otherwise it is evaluated as a C constant, with the following extensions:
-.Pp
-.Bl -bullet -offset indent -compact
-.It
-A leading plus or minus sign is allowed.
-.It
-If the leading character is a single or double quote, the value is the
-.Tn ASCII
-code of the next character.
-.El
-.Pp
-The format string is reused as often as necessary to satisfy the
-.Ar arguments  .
-Any extra format specifications are evaluated with zero or the null
-string.
-.Pp
-Character escape sequences are in backslash notation as defined in
-.St -ansiC .
-The characters and their meanings are as follows:
-.Bl -tag -width Ds -offset indent
-.It Cm \ee
-Write an \*[Lt]escape\*[Gt] character.
-.It Cm \ea
-Write a \*[Lt]bell\*[Gt] character.
-.It Cm \eb
-Write a \*[Lt]backspace\*[Gt] character.
-.It Cm \ef
-Write a \*[Lt]form-feed\*[Gt] character.
-.It Cm \en
-Write a \*[Lt]new-line\*[Gt] character.
-.It Cm \er
-Write a \*[Lt]carriage return\*[Gt] character.
-.It Cm \et
-Write a \*[Lt]tab\*[Gt] character.
-.It Cm \ev
-Write a \*[Lt]vertical tab\*[Gt] character.
-.It Cm \e\'
-Write a \*[Lt]single quote\*[Gt] character.
-.It Cm \e"
-Write a \*[Lt]double quote\*[Gt] character.
-.It Cm \e\e
-Write a backslash character.
-.It Cm \e Ns Ar num
-Write an 8\-bit character whose
-.Tn ASCII
-value is the 1\-, 2\-, or 3\-digit octal number
-.Ar num .
-.It Cm \ex Ns Ar xx
-Write an 8\-bit character whose
-.Tn ASCII
-value is the 1\- or 2\-digit hexadecimal number
-.Ar xx .
-.El
-.Pp
-Each format specification is introduced by the percent character
-(``%'').
-The remainder of the format specification includes,
-in the following order:
-.Bl -tag -width Ds
-.It "Zero or more of the following flags:"
-.Bl -tag -width Ds
-.It Cm #
-A `#' character
-specifying that the value should be printed in an ``alternative form''.
-For
-.Cm b ,
-.Cm c ,
-.Cm d ,
-and
-.Cm s
-formats, this option has no effect.
-For the
-.Cm o
-format the precision of the number is increased to force the first
-character of the output string to a zero.
-For the
-.Cm x
-.Pq Cm X
-format, a non-zero result has the string
-.Li 0x
-.Pq Li 0X
-prepended to it.
-For
-.Cm e  ,
-.Cm E ,
-.Cm f  ,
-.Cm g ,
-and
-.Cm G
-formats, the result will always contain a decimal point, even if no
-digits follow the point (normally, a decimal point only appears in the
-results of those formats if a digit follows the decimal point).
-For
-.Cm g
-and
-.Cm G
-formats, trailing zeros are not removed from the result as they
-would otherwise be.
-.\" I turned this off - decided it isn't a valid use of '#'
-.\" For the
-.\" .Cm B
-.\" format, backslash-escape sequences are expanded first;
-.It Cm \&\-
-A minus sign `\-' which specifies
-.Em left adjustment
-of the output in the indicated field;
-.It Cm \&+
-A `+' character specifying that there should always be
-a sign placed before the number when using signed formats.
-.It Sq \&\ \&
-A space specifying that a blank should be left before a positive number
-for a signed format.
-A `+' overrides a space if both are used;
-.It Cm \&0
-A zero `0' character indicating that zero-padding should be used
-rather than blank-padding.
-A `\-' overrides a `0' if both are used;
-.El
-.It "Field Width:"
-An optional digit string specifying a
-.Em field width ;
-if the output string has fewer characters than the field width it will
-be blank-padded on the left (or right, if the left-adjustment indicator
-has been given) to make up the field width (note that a leading zero
-is a flag, but an embedded zero is part of a field width);
-.It Precision :
-An optional period,
-.Sq Cm \&.\& ,
-followed by an optional digit string giving a
-.Em precision
-which specifies the number of digits to appear after the decimal point,
-for
-.Cm e
-and
-.Cm f
-formats, or the maximum number of characters to be printed
-from a string
-.Sm off
-.Pf ( Cm b Ns \&,
-.Sm on
-.Cm B
-and
-.Cm s
-formats); if the digit string is missing, the precision is treated
-as zero;
-.It Format :

-.El
-.Pp
-A field width or precision may be
-.Sq Cm \&*
-instead of a digit string.
-In this case an
-.Ar argument
-supplies the field width or precision.
-.Pp
-The format characters and their meanings are:
-.Bl -tag -width Fl
-.It Cm diouXx
-The
-.Ar argument
-is printed as a signed decimal (d or i), unsigned octal, unsigned decimal,
-or unsigned hexadecimal (X or x), respectively.
-.It Cm f
-The
-.Ar argument
-is printed in the style
-.Sm off
-.Pf [\-]ddd Cm \&. No ddd
-.Sm on
-where the number of d's
-after the decimal point is equal to the precision specification for
-the argument.
-If the precision is missing, 6 digits are given; if the precision
-is explicitly 0, no digits and no decimal point are printed.
-.It Cm eE
-The
-.Ar argument
-is printed in the style
-.Sm off
-.Pf [\-]d Cm \&. No ddd Cm e No \\*(Pmdd
-.Sm on
-where there
-is one digit before the decimal point and the number after is equal to
-the precision specification for the argument; when the precision is
-missing, 6 digits are produced.
-An upper-case E is used for an `E' format.
-.It Cm gG
-The
-.Ar argument
-is printed in style
-.Cm f
-or in style
-.Cm e
-.Pq Cm E
-whichever gives full precision in minimum space.
-.It Cm b
-Characters from the string
-.Ar argument
-are printed with backslash-escape sequences expanded.
-.br
-The following additional backslash-escape sequences are supported:
-.Bl -tag -width Ds
-.It Cm \ec
-Causes
-.Nm
-to ignore any remaining characters in the string operand containing it,
-any remaining string operands, and any additional characters in
-the format operand.
-.It Cm \e0 Ns Ar num
-Write an 8\-bit character whose
-.Tn ASCII
-value is the 1\-, 2\-, or 3\-digit
-octal number
-.Ar num .
-.It Cm \e^ Ns Ar c
-Write the control character
-.Ar c .
-Generates characters `\e000' through `\e037`, and `\e177' (from `\e^?').
-.It Cm \eM\- Ns Ar c
-Write the character
-.Ar c
-with the 8th bit set.
-Generates characters `\e241' through `\e376`.
-.It Cm \eM^ Ns Ar c
-Write the control character
-.Ar c
-with the 8th bit set.
-Generates characters `\e000' through `\e037`, and `\e177' (from `\eM^?').
-.El
-.It Cm B
-Characters from the string
-.Ar argument
-are printed with unprintable characters backslash-escaped using the
-.Sm off
-.Pf ` Cm \e Ar c No ',
-.Pf ` Cm \e^ Ar c No ',
-.Pf ` Cm \eM\- Ar c No '
-or
-.Pf ` Cm \eM^ Ar c No ',
-.Sm on
-formats described above.
-.It Cm c
-The first character of
-.Ar argument
-is printed.
-.It Cm s
-Characters from the string
-.Ar argument
-are printed until the end is reached or until the number of characters
-indicated by the precision specification is reached; if the
-precision is omitted, all characters in the string are printed.
-.It Cm \&%
-Print a `%'; no argument is used.
-.El
-.Pp
-In no case does a non-existent or small field width cause truncation of
-a field; padding takes place only if the specified field width exceeds
-the actual width.
-.Sh EXIT STATUS
-.Nm
-exits 0 on success, 1 on failure.
-.Sh SEE ALSO
-.Xr echo 1 ,
-.Xr printf 3 ,
-.Xr printf 9 ,
-.Xr vis 3
-.Sh STANDARDS
-The
-.Nm
-utility conforms to
-.St -p1003.1-2001 .
-.Pp
-Support for the floating point formats and `*' as a field width and precision
-are optional in POSIX.
-.Pp
-The behaviour of the %B format and the \e', \e", \exxx, \ee and
-\e[M][\-|^]c escape sequences are undefined in POSIX.
-.Sh BUGS
-Since the floating point numbers are translated from
-.Tn ASCII
-to floating-point and
-then back again, floating-point precision may be lost.
-.Pp
-Hexadecimal character constants are restricted to, and should be specified
-as, two character constants.
-This is contrary to the ISO C standard but
-does guarantee detection of the end of the constant.

-.Sh NAME
-.Nm test ,
-.Nm \&[
-.Nd condition evaluation utility
-.Sh SYNOPSIS
-.Nm test
-.Ar expression
-.Nm \&[
-.Ar expression Cm \&]
-.Sh DESCRIPTION
-The
-.Nm test
-utility evaluates the expression and, if it evaluates
-to true, returns a zero (true) exit status; otherwise
-it returns 1 (false).
-If there is no expression, test also
-returns 1 (false).
-.Pp
-All operators and flags are separate arguments to the
-.Nm test
-utility.
-.Pp
-The following primaries are used to construct expression:
-.Bl -tag -width Ar
-.It Fl b Ar file
-True if
-.Ar file
-exists and is a block special
-file.
-.It Fl c Ar file
-True if
-.Ar file
-exists and is a character
-special file.
-.It Fl d Ar file
-True if
-.Ar file
-exists and is a directory.
-.It Fl e Ar file
-True if
-.Ar file
-exists (regardless of type).
-.It Fl f Ar file
-True if
-.Ar file
-exists and is a regular file.
-.It Fl g Ar file
-True if
-.Ar file
-exists and its set group ID flag
-is set.
-.It Fl h Ar file
-True if
-.Ar file
-exists and is a symbolic link.
-.It Fl k Ar file
-True if
-.Ar file
-exists and its sticky bit is set.
-.It Fl n Ar string
-True if the length of
-.Ar string
-is nonzero.
-.It Fl p Ar file
-True if
-.Ar file
-is a named pipe
-.Po Tn FIFO Pc .
-.It Fl r Ar file
-True if
-.Ar file
-exists and is readable.
-.It Fl s Ar file
-True if
-.Ar file
-exists and has a size greater
-than zero.
-.It Fl t Ar file_descriptor
-True if the file whose file descriptor number
-is
-.Ar file_descriptor
-is open and is associated with a terminal.
-.It Fl u Ar file
-True if
-.Ar file
-exists and its set user ID flag
-is set.
-.It Fl w Ar file
-True if
-.Ar file
-exists and is writable.
-True
-indicates only that the write flag is on.
-The file is not writable on a read-only file
-system even if this test indicates true.
-.It Fl x Ar file
-True if
-.Ar file
-exists and is executable.
-True
-indicates only that the execute flag is on.
-If
-.Ar file
-is a directory, true indicates that
-.Ar file
-can be searched.
-.It Fl z Ar string
-True if the length of
-.Ar string
-is zero.
-.It Fl L Ar file
-True if
-.Ar file
-exists and is a symbolic link.
-This operator is retained for compatibility with previous versions of
-this program.
-Do not rely on its existence; use
-.Fl h
-instead.
-.It Fl O Ar file
-True if
-.Ar file
-exists and its owner matches the effective user id of this process.
-.It Fl G Ar file
-True if
-.Ar file
-exists and its group matches the effective group id of this process.
-.It Fl S Ar file
-True if
-.Ar file
-exists and is a socket.
-.It Ar file1 Fl nt Ar file2
-True if
-.Ar file1
-exists and is newer than
-.Ar file2 .
-.It Ar file1 Fl ot Ar file2
-True if
-.Ar file1
-exists and is older than
-.Ar file2 .
-.It Ar file1 Fl ef Ar file2
-True if
-.Ar file1
-and
-.Ar file2
-exist and refer to the same file.
-.It Ar string
-True if
-.Ar string
-is not the null
-string.
-.It Ar \&s\&1 Cm \&= Ar \&s\&2
-True if the strings
-.Ar \&s\&1
-and
-.Ar \&s\&2
-are identical.
-.It Ar \&s\&1 Cm \&!= Ar \&s\&2
-True if the strings
-.Ar \&s\&1
-and
-.Ar \&s\&2
-are not identical.
-.It Ar \&s\&1 Cm \&\*[Lt] Ar \&s\&2
-True if string
-.Ar \&s\&1
-comes before
-.Ar \&s\&2
-based on the ASCII value of their characters.
-.It Ar \&s\&1 Cm \&\*[Gt] Ar \&s\&2
-True if string
-.Ar \&s\&1
-comes after
-.Ar \&s\&2
-based on the ASCII value of their characters.
-.It Ar \&n\&1 Fl \&eq Ar \&n\&2
-True if the integers
-.Ar \&n\&1
-and
-.Ar \&n\&2
-are algebraically
-equal.
-.It Ar \&n\&1 Fl \&ne Ar \&n\&2
-True if the integers

-is algebraically less
-than the integer
-.Ar \&n\&2 .
-.It Ar \&n\&1 Fl \&le Ar \&n\&2
-True if the integer
-.Ar \&n\&1
-is algebraically less
-than or equal to the integer
-.Ar \&n\&2 .
-.El
-.Pp
-These primaries can be combined with the following operators:
-.Bl -tag -width Ar
-.It Cm \&! Ar expression
-True if
-.Ar expression
-is false.
-.It Ar expression1 Fl a Ar expression2
-True if both
-.Ar expression1
-and
-.Ar expression2
-are true.
-.It Ar expression1 Fl o Ar expression2
-True if either
-.Ar expression1
-or
-.Ar expression2
-are true.
-.It Cm \&( Ns Ar expression Ns Cm \&)
-True if expression is true.
-.El
-.Pp
-The
-.Fl a
-operator has higher precedence than the
-.Fl o
-operator.
-.Sh GRAMMAR AMBIGUITY
-The
-.Nm test
-grammar is inherently ambiguous.
-In order to assure a degree of consistency, the cases described in
-.St -p1003.2
-section 4.62.4,
-are evaluated consistently according to the rules specified in the
-standards document.
-All other cases are subject to the ambiguity in the command semantics.
-.Sh EXIT STATUS
-The
-.Nm test
-utility exits with one of the following values:
-.Bl -tag -width Ds
-.It 0
-expression evaluated to true.
-.It 1
-expression evaluated to false or expression was
-missing.
-.It \*[Gt]1
-An error occurred.
-.El
-.Sh STANDARDS
-The
-.Nm test
-utility implements a superset of the
-.St -p1003.2
-specification.

Subject: [PATCH 08/14] debian/apertis/copyright: Drop trailing empty line to
 make CI happy

The scan-licenses job on the Bookworm-based v2023dev3 branch now really
insists in eliminating the empty line it previously left at the bottom
of the `debian/apertis/copyright` file.
