# Shell script to automate the creation of new templates for pkgfs.
# Only writes basic stuff into the template, if you need advanced stuff
# you'll have to do that manually.
#
# At least it will fetch the distfile and compute the checksum, plus
# other stuff for free... so it's not that bad, heh.
#
# Supports GNU configure, configure and perl module templates for now.
