+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

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

+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
+  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]

+  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
+  --with-libedit          Compile with libedit support
+
+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
+
+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.

+Please tell bug-automake@gnu.org about your system, including the value

- The system shell is the default command interpreter for shell scripts.

- users.
-# _Description: Install dash as /bin/sh?
-#  The default /bin/sh shell on Debian and Debian-based systems is bash.

-#  However, since the default shell is required to be POSIX-compliant,

-#  You may wish to do this because dash is faster and smaller than bash.

+Subject: Update manpages
+
+man: Fix getopts documentation
+
+  The explicit arguments were missing, also exchange expr subst for
+  arithmetic and fix the spacing around Bell Labs
+
+man: Document jobs builtin
+
+man: Note chdir being the same builtin as cd
+
+man: Document kill builtin
+
+The manual now contains all built-ins
+
+man: Reword to avoid confusion v/v printf Ar argument[s]/arguments
+
+  The current wording says that given
+    printf a b c d
+  a is the format, c and d are processed as noted,
+  but b is unspecified
+
+man: printf 'X, X is a byte under dash
+
+  Multiple issues:
+    * the encoding is not always ASCII
+    * what ASCII code is assigned to я
+    * dash isn't internationalised
+      (this is nonconformant but out of scope),
+      and uses the next /byte/; in a UTF-8 locale:
+        $ printf %d\\n \'Ä…
+        196
+        $ printf %d\\n \'я
+        196
+      this is in contrast to POSIX (and bash), which says:
+        > If the leading character is a single-quote or double-quote,
+        > the value shall be the numeric value in the underlying codeset
+        > of the character following the single-quote or double-quote.
+      (i.e. mbrtowc(&val, argv[n], ...))
+
+man: Document false built-in
+
+  Only true was documented, add false just below it
+  (out of order, but so is true, and the grouping makes much more sense).
+
+man: Document ulimit -w

-Subject: [PATCH] jobs: Only block in waitcmd on first run
-Message-ID: <20201202053145.GA8074@gondor.apana.org.au>
-
-This patch ensures that waitcmd never blocks unless there are
-outstanding jobs.  This could otherwise trigger a hang if children
-were created prior to the shell coming into existence, or if
-there are backgrounded children of other kinds (e.g., a here-
-document).

+##   up in a subdir.  Having to rename by hand is ugly.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse
+##   than renaming).

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.

-#	@(#)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 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.

-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.

-.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:

-.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 w Ar file
-True if
-.Ar file
-exists and is writable.
-True

-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.

-.It Fl z Ar string
-True if the length of
-.Ar string
-is zero.
-.It Fl L Ar file
-True if
-.Ar file

-.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.
