+Math::Base85 - Perl extension for base 85 numbers, as referenced by RFC 1924
+
+RFC 1924 describes a compact, fixed-size representation of IPv6 addresses
+which uses a base 85 number system. This module handles some of the uglier
+details of it.

+# 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 ':'.
