I downloaded this program and tried it out. It definitely
has possibilities. I especially like its flexible prefix feature,
which should make it possible to use for source files in just
about any language. You could use this, for instance, to pre-process
SQL scripts for different DBMSs. I've been doing stuff like this
using sed scripts in makefiles, and I can tell you I'd much rather
do it this way.
Thanks for the tip.
