Depends of course on what they are doing, but for those which work on  
text, let it read from DATA instead of STDIN and put your sample  
input at the bottom of the script (after __END__) -- that way you can  
run it in TM and use the normal debug techniques.

Example:

     # quote input/selection
     text = DATA.read # change to STDIN.read when deploying
     puts text.gsub(/^/, '> ')

     __END__
