[p4] hm. files that should be version-controlled.

[Arnt Gulbrandsen]

It occured to me today that many years ago, when using RCS and some sh 
wrappers to do the job of a source control system, we had a simple 
script to deal with this.

The script did:
1. Ask the build system what files it needs in order to build.
2. Ask the version control system what files it manages.
3. Subtract 2 from 1 and complain if there's anything left over.

Not patentable, I should think.

I wrote the same thing for jam+p4 now, as a work avoidance tactic if 
truth be told. It was easy. A little bit of perl line noise. Much more 
fun than my work today, and also much more fun than complaining on 
perforce-user that the build breaks because people forget to p4 add.
