What is the correct way to load a Ruby script into the
top-level namespace?

In other words, from within a script, I want to simulate
the behavior of having called the script on the command-line,
such as "ruby myscript.rb"...  From within another script,
how do I load "myscript.rb" into the top-level namespace?

Thanks!  (I couldn't find this by searching the RubyGarden
or the RubyWiki... sorry if this is a FAQ.)
