I just stumbled across this sentence,

  Any UNIX command or script, including those
  written in sh, tcsh, bash, tcl, Perl, or Ruby
  as well as AppleScript, can be accessed from
  the widget object.

while reading about Apple's Dashboard widgets,

  http://developer.apple.com/macosx/dashboard.html

I wasn't so much surprised by the mention of Ruby,
but by the lack of other languages...

In the past, it was more common to see sentence.
gsub(/Ruby/,''), sentence.gsub(/Ruby/,'Python'), or
sentence.gsub(/Ruby/,'Python, Ruby').
