# Your Vector Linux .tlz package, slack-desc, and slack-required will be found in "VERSION" dir.
# The extraction and build will be in a temp dir created in "NAME" dir, and then removed on exit.
# Comment out last line to keep this dir intact.

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

# Now this is where my script get's weird.  We need to generate a set of udev rules so the users system will

# to make a temporary package, install it on our build machine, generate a set of rules to include them into
# the "real" package.  Then remove the temp package from our machine, and package up a "real" package containing
# the udev rules.  I've tried using the uninstalled files to generate, but naturally nothing runs because of 
# the paths aren't correct. If you come up with a better solution... go for it.
