Ah, yes, right... That shook loose some ancient information, from back when I was using CVS.

As I recall, CVS has some magic such that $Revision nnn$ will be automatically updated, replacing nnn will the current CVS revision number each time you check the file in.

The rest of the code is to extract the number from the string $Revision nnn$ and reformat it so that each number (after the first) is displayed as two digits. So $Revision 1.2.3.4.5$ becomes 1.02.03.04.05.
