I have been playing with the idea of using cpp to pre-process such
files, and maybe even put them in a Makefile. I don't think there's
any reason that wouldn't be possible with SQL files. Added bonus, you
can use macros in your SQL, for things like environment paths (for
including other SQL files for example) etc.
