What's the easiest way to figure out if you are on a Windows vs. UNIX
platform in Ruby from within a Ruby program?
Thanks,

Try this:
irb(main):005:0> puts RUBY_PLATFORM
powerpc-darwin8.0

Not very useful sometimes:
irb(main):001:0> puts RUBY_PLATFORM
i386-mswin32_71
(1) (2) (3)(4)
Here's encoded: CPU architecture (1), OS (2), CPU bits (3), compiler (4 -
it's MS Visual Studio 7.1)
Pasing this on every platform may become a pain.

RUBY_PLATFORM is pretty good, but don't forget about the 'rbconfig'
module either.
puts RUBY_PLATFORM # => 'i386-linux'
require 'rbconfig'
puts Config::CONFIG['target_cpu'] # => 'i386'
puts Config::CONFIG['target_os'] # => 'linux'
puts Config::CONFIG['host_cpu'] # => 'i686'
puts Config::CONFIG['host_os'] # => 'linux-gnu'
good stuff there.

Plug around in the 'rbconfig' module, see if any of the items in there
work better.
