Sheer ignorance and haste on my part :-)

The convention the installer uses is that .rbw files
are GUI programs and .rb files are console.  If the default
handled the normal (F5) execution based on the suffix, then
we could have an extra tools entry for "run it in a console
anyway".

Does that sound reasonable?
