question about adding

Recently I undertook writing a function of a script that needed to tell if a
file was more than x number of minutes old.  Quite simple, but a dastardly
trick to do in ksh.  (well, with my limited knowledge)  Instead, I turned to
a c++ programmer friend, and of course he churned out a simple c++ program
in no time.  Simple, effective.  Does one task, and does it well.  Remind
you of anything?

He's informed me that he has no problem gpl'ing it, and so I ask you -- What
should I do with this thing?  It's not a 'project' in any sense of the word,
but i feel it's incredibly useful.
