platform.rb (was: PLATFORM tests)

[Kaspar Schiess]

Hi,

Matt Mower has developed a PLATFORM matching library that seems quite
aedequate in fact. I have extended it with the suggestions of the list and
also those that I have received privately.

You can find the new platform detection library here:
http://tua.ch/ruby/current.html
or a direct link
http://tua.ch/ruby/platform/platform.zip

Please pluck that apart and help me reconstruct something that you'd
actually use.

best regards,
kaspar
