# This SlackBuild like script is designed for Vector Linux packages by exeterdad.

# This script assumes it will be launched within "/NAME/VERSION/src" dir.  With all sources in "src"
# 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.
# Thanks to slacky.it for some code

# 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 ':'.
