(ms) Added documentation for multiple data sources and archives. (ms) Martin Kurahaupo <martin@kurahaupo.gen.nz> added a patch to prevent the test suite from failing when run as root because a test file can't be write-protected. (ms) Chris Fedde <cfedde@denver.pm.org> provided a patch to structure ::info's output more perl-like. Got input from perlmonks (thanks nobull!) on how to efficiently transform RRDTools info output into Perl data structures.
