network-wide graphing framework (common)

 Munin is a highly flexible and powerful solution used to create graphs of
 virtually everything imaginable throughout your network, while still
 maintaining a rattling ease of installation and configuration.
 .
 This package contains the common perl modules that are used by both munin
 and munin-node.
 .
 Munin is written in Perl, and relies heavily on Tobi Oetiker's excellent
 RRDtool. To see a real example of Munin in action, you can follow a link
