[Mono-list] Detecting available runtimes

[Charlie Poole]

Hi All,

I'm looking for some code to detect what CLRs are available,
so I can offer the choice for running tests in NUnit. 

On Linux, I need to detect what versions of Mono are available.

On Windows, I need to do that and also detect installed versions
of MS .NET. 

I know how to go about it on Windows, via the registry, but not
on Linux. Ideally, I'd like to grab some code out of some other
app with a permissive license.

Has anyone done this?
