Do what Eli said.  But a word of caution:  If you're trying to write
the user's document on a "save" command, you must use a temp file
with  delete/rename; otherwise, if the computer crashes or the mains
die while you're writing the data, the user's precious data is
irretrievably lost (lawsuit!).  Yes, I'm just bitter that GIMP for
Windows has eaten some of my files.
