Simple script that makes life a little easier with gnu-autotools
on FreeBSD. Configgen takes all the guess work out of figuring out
paths, gnu-autotools versions, and more. Configgen can simply be
run in a source directory and it will figure out which versions of
autotools to use and the best way to auto-generate a configure script
or you can specify a command below.

 -gnu       Create generic gnu configure script
 -gnome     Create gnome specific configure script
 -bsd       Use FreeBSD auto-tools
              (versions: libtool, automake-1.5, autoconf-2.53)
 -bsd14     Use FreeBSD auto-tools
              (versions: libtool, automake-1.4, autoconf-2.13)
 -bsd19     Use FreeBSD auto-tools
              (versions: libtool, automake-1.9, autoconf-2.59)
 -bsd110    Use FreeBSD auto-tools
	      (versions: libtool, automake-1.10, autoconf-2.61)
 -f         Find config (fall back on generic gnu)
 <config>   Specify a auto-gen configure script
