## 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 ':'.
