# 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 tmp dir created in "VERSION" dir, and then removed on exit.     #
# Comment out the second to last line to keep this dir intact for inspection.                           #
#                                                                                                       #
# Please be kind. A master build script may be passing variables to this SlackBuild. If you are	        #
# using this script alone, please only change the "X's" in these four variables. Leave the surrounding  #
# code 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 ':'.
