WowCardioRaid is an offline standalone parser for analyzing the wow combat log output.
It's not an Addon, but a full external application. So, *do not* use CurseClient to get it, because this tool has nothing to do in the wow addon folder.

This tool supports LiveUpdate and realtime parsing.
A full intruvion manual is included in the distribution.

-launch the program
-load a WowCombatlog.txt file. Logs are located in the .\logs repertory of World of warcraft. (WCR supports live log parsing)
-watch and analyse the log in the graphic viewport throught multiple filters systems
-You can Zoom and dezoom on the timeline, select time period, select spell or event. It basically shows everything
-You can see a stats breakdown for the selected period of time.

It only works on windows. Beta version and Sources can be found at http://tixu.scribe.free.fr/
