-# 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 ':' except on otherwise blank lines.
