Extracting SCCS Metrics

[Jim Roche]

I want to extract metrics from the SCCS directory for a largish
(250KLOC) Unix project.  Some of the things I would like to get are:
   - number of lines changed between two dates 
   - number of lines changed between two releases
   - above for entire project, subprojects (file subset), files
   - etc. (you can't manage what you can't measure)

I would like to count uncommented lines of code or statements (I've
got a tool to do that already) instead of the numbers that sccs prs
gives me.  I'd also like to extract some of the metrics on a regular
basis (e.g. using crontab).

Does anyone have tools that do this sort of stuff, or know where they
are available?  Please mail me (jimr at newbridge.com) and I will
summarize.  TIA (Thanks In Advance).

P.S.  Lets not resurrect the "lines of code is a useless metric"
      argument :-)
