We have the requirement that we need to be able identify the exact set of source filenames that were accessed during a build, and deliver only those source files to a customer. In my previous experience using ClearCase, I remember that it had two ways of doing this: using the integrated clearmake, or running ordinary make within an audited shell script. I've asked Perforce tech support about this, and there is nothing corresponding available in Perforce (it doesn't fit the model). I was wondering if other Perforce users have had a similar requirement, and if so, how they worked around it. Thanks, Glenn
