Reimport of autoswc, version 1.0, coming from sysutils:

autoswc is an utility that automatically generates system wide cache files
for use with configure scripts created by GNU autoconf, and specially by
those executed within pkgsrc.

Reason for the move: pkgtools' Makefile says this category is for packages
used within pkgsrc.  autoswc is specially designed to work for pkgsrc, so
it is better placed here.  And it may get more exposure ;-)

+.Sh NAME
+.Nm autoswc
+.Nd generates system wide cache files for GNU autoconf
+.Sh SYNOPSIS
+.Nm
+.Op Fl c Ar ac_file
+.Op Fl n Ar cache_name
+.Sh DESCRIPTION
+.Nm
+is an utility that automatically generates system wide cache files for use
+with configure scripts created by
+.Nm GNU autoconf ,
+and specially by those executed within
+.Nm pkgsrc .
+.Pp
+.Nm
+starts by reading the configuration script template.
+It will use
+.Pa @SYSCONFDIR@/configure.ac
+if found, or fallback to
+.Pa @PREFIX@/share/autoswc/configure.ac
+otherwise (a custom file may be given using the
+.Fl c
+flag, though).
+This issues all checks that the user wants to store in the system wide
+cache file, and are basically calls to standard
+.Nm GNU autoconf ,
+.Nm GNU automake
+and/or
+.Nm GNU libtool
+macros.
+There is no need to manually execute any of the
+.Sq AC_INIT ,
+.Sq AM_INIT_AUTOMAKE ,
+.Sq AC_CACHE_SAVE
+and
+.Sq AC_OUTPUT
+macros, as they are automatically inserted in the right place during
+execution.
+.Pp
+The default cache file is stored inside the
+.Pa @CACHEDIR@
+directory, using
+.Pa config.cache.default
+as the file name.
+The
+.Sq default
+part can be changed using the
+.Fl n
+flag, which takes the base name of the cache file.
+.Pp
+To tell
+.Nm pkgsrc
+to use the system wide cache, all you need to do is append the following
+line to your
+.Pa @MKCONF@
+file:
+.Bd -literal -offset indent
+\&.sinclude "@PREFIX@/share/autoswc/autoswc.mk"
+.Ed
+.Pp
+In case you used the
+.Fl n
+flag, you also need to define the
+.Va AUTOSWC_CACHE_NAME
+variable in this file, setting it to the value passed to the flag.
+.Sh NOTES
+Be very careful about what you add to
+.Pa configure.ac .
+You should only check for things that are unlikely to change over time,
+as functions in the
+.Lb libc
+and its header files.
+Failure to do so can easily lead to cache files that get outdated very
+easily during installation of new packages, and cause unexpected
+configuration errors.
+.Pp
+It is recommended that you rebuild the cache file periodically.
+You can configure a simple
+.Xr cron 8
+job to it, which just needs to launch this utility.
+.Pp
+If you hit a compilation problem in any package when using
+.Nm ,
+be
+.Em absolutely
+sure it is not beeing caused by an outdated cache before reporting
+problems.
+The safest and easiest way to do this is to clean the package in question
+and restart the build with the
+.Va AUTOSWC_DISABLE
+variable set, like in the following example:
+.Bd -literal -offset indent
+$ @MAKE@ clean
+$ @MAKE@ AUTOSWC_DISABLE=YES
+.Ed
