  28 # Shell script to automate the creation of new templates for pkgfs.
  29 # Only writes basic stuff into the template, if you need advanced stuff
  30 # you'll have to do that manually.
  31 #
  32 # At least it will fetch the distfile and compute the checksum, plus
  33 # other stuff for free... so it's not that bad, heh.
  34 #
  35 # Supports GNU configure, configure and perl module templates for now.
