[mrtg] Routers2 for MRTG/RRD v2.20 released

[Steve Shipway]

At long last (well, it's been almost a year) I'm able to release version 2.20 of the Routers2 frontend for MRTG/RRD.  This should be a drop-in replacement for earlier 2.x versions, and has been tested with Perl 5.10 and RRDTool 1.3.6.

This new version includes a number of bug fixes, several enhancements and some new features.  Highlights include:
* Much enhanced symbol replacement in Pagetop/Pagefoot
* New graph style 'lines'
* logscale support added
* Secondary Y-axis support added (RRDTool 1.3.x only, experimental)
* Compact summry now uses stylesheets instead of external images
  which improves speed considerably and removes GD.pm dependency
* MySQL authentication module added

As always, support is available on http://www.steveshipway.org/forum and via email. There has been extensive testing, but due to the many different permutations of system configurations there is always the possibility that something has been overlooked, so if you find any issues, please let me know as soon as possible to get them corrected.

The Routers2/MRTG/RRD book, http://www.steveshipway.org/book edition 2 includes all the new directives up to beta5.  If you don't yet have a copy, please buy one and help support development!

The support for a secondary Y-Axis (so you can have a temperature graph in deg C and deg F simultaneously, or show traffic and errors on the same graph with different scales) was added after much user requests when the required features were added to the RRDTool API in v1.3.x.  Although heavily tested, this support should still be regarded as experimental.

Version 2.20 is dedicated to the memory of my father, Jolyon Shipway, who always supported and encouraged me throughout my life.  He passed away this year at the age of 70 from lung cancer as the direct result of a lifetime of smoking.

Thankyou for your time and support,

Steve
