Thanks for the pointer. I did actually look for a library by you
because someone mentioned in IRC that you'd done something along these
lines.

It seems like this provides a lot better information than I can get
from RUBY_PLATFORM but is in the form of a C extension which doesn't
suit me. It might be exactly right for some other folks though.

Regards,

Matt

If it helps soothe your mind, the Win32 version is pure Ruby. :)

PS - I updated the description of sys-uname on the RAA, so hopefully
folks will discover it a little easier in the future.

I'm not clear what this means. Can it be distributed as a gem for use
on Windows ,Unix, and other platforms?

That's a good idea.
