A neat way to do this would be with a shell script, as there is no in built text processing in gschem. I personally feel that the place for this processing would be (for now at least) in a user's Makefile or post-processing script. A little bit of "sed" or "awk" usage in conjunction with some /usr/bin/sh scripting should do the trick. In future, we might support more flexible extensibility. In theory, we could provide a hook for calling scheme code on file-save, however the APIs are not really "there" enough yet to do the manipulation you're after.
