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 ;-)
