your files via `
cvs status' and `
But as soon as you export the files from your
development environment it becomes harder to identify
which revisions they are.

identifying the files. Embedded strings of the form
$keyword:...$ in a file are replaced
with strings of the form
$keyword:value$ whenever you obtain
a new revision of the file.
