Thanks for your answer, I think I get what you're talking about but it is not the case for me. First, we have here a mixture of linuxes and macs, so I can't just make an executable bundle. Second, yes, I did really visible thing, you really have to be blind not to see it; visible, but still unwanted and therefore useless.
Our management doesn't want to hear about perl - they believe that perl not only useless but dangerous, because 'it hard to maintain and support'. 'You can write the perl code', they say, 'but you can't read it'.
