# HOW TO EDIT THIS FILE:
# The "handy ruler" below kanshis 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
# kanshi exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.
