Keyword substitution

As long as you edit source files inside a working directory you can always find out the state of your files via `cvs status' and `cvs log'. But as soon as you export the files from your development environment it becomes harder to identify which revisions they are.

CVS can use a mechanism known as keyword substitution (or keyword expansion) to help identifying the files. Embedded strings of the form $keyword$ and $keyword:...$ in a file are replaced with strings of the form $keyword:value$ whenever you obtain a new revision of the file.
