Eclipse toolchains (how to?)

I want to use Eclipse to develop software in windows for an ARM Cortex-M3 based processor (Stellaris fury class) and I can’t figure out how to create my own toolchain in Eclipse for ARM Stellaris processors. Has anyone created a toolchain in Eclipse and could possibly give me some tips? I hate having to start with the default toolchain and changing all the options for every project, it can be quite error prone…

Oh this is for Eclipse Europa (v3.3 CDT v4.0) btw, as I understand things changed in europa? I keep getting conflicting infos in my web searches…

Thanks in advance for any possible help on this!
