There are better alternatives. I've written several myself. Right now I 
have two, one I wrote to use and one I wrote because I was really bored 
that day, much better than the first one. It uses the following, highly 
complex algorithm:

1. Ask the build system which files are necessary to build.
2. Ask p4 which files are version-controlled.
3. a-b.

I expect everyone here can implement that algorithm for their build 
system without expending too many grey cells. (But if you use jam, you 
can have a copy of mine.)
