This is Munin::Master::HTMLOld, a minimal package shell to make
munin-html modular (so it can loaded persistently in
munin-fastcgi-graph for example) without making it object oriented
yet. The non-"old" module will feature propper object orientation
like munin-update and will have to wait until later.

This is the hierarchy of templates
* munin-overview.tmpl - Overview with all groups and hosts shown (2 levels down)
* munin-domainview.tmpl - all members of one domain, showing links down to each single service
and/or sub-group
* munin-nodeview.tmpl - two (=day, week) graphs from all plugins on the node
* munin-serviceview.tmpl - deepest level of view, shows all 4 graphs from one timeseries
* Zoom view - zoomable graph based on one of the other four graphs
OR
* munin-nodeview.tmpl - multigraph sub-level. When multigraph sublevels end ends
the next is a munin-serviceview.
* Comparison pages (x4) are at the service level. Not sure how to work multigraph into them so
avoid it all-together.

Munin-html is a part of the package Munin, which is used in combination
with Munin's node. Munin is a group of programs to gather data from
Munin's nodes, graph them, create html-pages, and optionally warn Nagios
about any off-limit values.
Munin-html creates the html pages.
