It can be done with a shell program, and should be.  We do this all the
time.  In practice doing it in sh is *more* flexible than doing it in C,
because there is less overhead in modifying it.  This sort of text
manipulation is a perfect application for shell programs.  Undoubtedly
one could devise cases complex enough to need C, but "don't fix it if
it ain't broken"!
