           # 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 ':'.
