Some people have mentioned that my sample-code was reformatted into
something close to useless by their email (or web-ized mail) clients.  So
here is a very simple "Hello World" script which includes my ruby-finding
strategy, along with some comments about how it works:

http://people.freebsd.org/~gad/tools/safe_ruby_script

(that is the actual script, and not a web page which displays the script, so
your web browser might simply download it as a file to your desktop)

I realize that it isn't a truly 100% perfect solution for every possible
situation,
but it has worked well over the past few years for me, writing scripts which
had to work reliably on several different platforms.
