The Platform library offers a simple, reliable, means of determining
what platform Ruby is running on. Underlying Platform is the
RUBY_PLATFORM constant. This library is parsing this constant for
information. You could easily do this yourself. We've just taken the
hassle out of it for you and hopefully covered a few of the more
unusual cases you mightn't have thought of yourself.
