Basically, just don't bother writing anything in there, as it will be 
overwritten anyway (see below).

This line is expanded by CVS during a commit, so you never edit it yourself. If 
you insert a line like
	# $Id: $
into a (text-)file and commit it into a CVS repository with activated keyword 
expansion, CVS will insert some information about the file into the Id - 
placeholder. The individual items within that line are:
	the filename where this $Id: $ line lives in
	the current CVS-revision of this file
	the date and time of last commit
	the name of the developer who did that commit
	the state (hm, what 'Exp' means in this context escapes me currently... ;-)

So, please do not change anything in that line, it will be replaced whenever 
you commit that file to a CVS-repository. If you are not going to do that 
anytime soon, you might choose to reduce that line to 
	# $Id: $
or even remove it completely.

cheers,
	Oliver
