+python-defaults (2.3.5-6) unstable; urgency=low
+
+  * Last 2.3.5 upload, 2.4.3 can be found in experimental.
+  * Do not build the python-mpz, python-tk and python-gdbm packages from
+    this source.
+  * Let the -all packages depend on the default packages (closes: #365219).
+  * Add /usr/share/python/debian_defaults for some default values (i.e.
+    the supported python versions).
+  * Add /etc/python/debian_config for byte-compilation options.
+  * Add a pyversions script to give information about python versions and
+    parse the XS-Python-Version attribute.
+  * Do not build the python-doc package from this source.

+.TH PYVERSIONS
+.SH NAME
+pyversions \- print python version information
+.SH SYNOPSIS
+.PP
+.B pyversions
+.I [-h] [-v] [<options>]
+.SH DESCRIPTION
+.PP
+.B pyversions
+prints information about installed, supported python runtimes, the
+default runtime, and parses the information of the PythonVersion
+fields in the package control file.
+.SH OPTIONS
+.TP
+.I -d, --default
+Show the default python version.
+.TP
+.I -s, --supported
+Show the supported python versions.
+.TP
+.I -r, --requested <version string> | <control file>
+Reads the
+.B XS-Python-Version
+value in the source section of a control file and shows all
+matching python versions. The parameter is interpreted as
+a version string, if it is not the name of a file.
+.TP
+.I -i, --installed
+Show the installed supported python versions.
+.TP
+.I -v, --version
+Limit the output to the version numbers of the python versions.
+.TP
+.I -h, --help
+Print a help text.
+.SH SEE ALSO
+Python policy.
