Action Bar Saver allows you to setup different profiles for your action bars. Mainly this is for hybrid classes that want to be able to respec without spending 10-20 minutes setting their action bars up.
All you do is type /abs save and it'll save the location of all your spells, macros and items.
For example, if you're currently a Feral Druid you can type /abs save feral then you can respec to Resto and setup your bars, then type /abs save resto once you go respec back to Feral you can then train all your spells again and type /abs restore feral and you'll get your feral setup without all the work of actually finding where you placed things.
Works with any custom interface like Bongos provided you're not using more then the standard 120 action buttons, ones that provided features to go past 120 will cause only the standard 120 to be saved/restored. This isn't a bug however, just a limitation in the WoW API

* Stripped all of the companion saving for 3.0, it doesn't work half the time and is ugly anyway
* Removed localization.deDE.lua and localization.frFR.lua not like I ever use them
