This is fatal - I use $Id$ all the time. We have some very large specification documents that we control using CVS, and it is critical when we read them that we know what version they are. We do the LaTeX equivalent of "set header to $Id$", and then all our documents are versioned.
Having the version anywhere else but in the document itself would be wrong, because they could get out of sync.
I'm told $Id$ expands to something like: $Id: Foo.hs,v 1.2 2003/03/04 03:22:34 myuser Exp $ OTTOMH I think the tuple (tagname (~= version), date of tag creation, e-mail address of tag creator) is unique and, along with the filename, is essentially the same information. To get around the modification of source files problem in Shae's URL perhaps "darcs flatten foo" or somesuch could be used to explicitly say "I'm taking foo away to print now so please expand $Id$ in it". It could complain if the current repo state isn't tagged (or prompt you for a name to tag it with) or if foo has unrecorded changes. Thanks Ian
