Subject: Where is RUBYOPT set?

This is on Windows XP:

Checking the RUBYOPT environment variable at a command prompt reveals
that it is set to "rubygems".

However, looking at the list of environment variables in "My
Computer/Properties/Advanced/Environment Variables" does not show
RUBYOPT listed at all (in either the "user variables" section or the
"system variables" section.

Is there somewhere else that it would have been picked up from?
