This is Debian GNU/Linux's prepackaged version of MIME::Base64 (renamed to be libmime-base64-perl). This is a set of perl modules which provide routines for manipulating Base64-encoded files. This package was put together by Michael Alan Dorman . The library is available from the Comprehensive Perl Archive Network (CPAN). Visit to find a CPAN site near you. The only change for the Debian package was the addition of the debian/ files.
