+# 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 blank lines.
