I'm guessing you'd like the editor to update the version. The version
string you are using here is one recognised by RCS (Revision Control System) and CVS (Concurrent Versioning System) which are both examples of Software Configuration Management tools. The idea with these systems is that you create a
repository of files. The repository stores a version history for each file. The 3 most common operations are:
[1] check a file out to modify
[2] check a file in after modifications
[3] export a project to deliver a set of files
The tool is responsible for making sure the $Id$ string in your file is automatically updated on checkout or export to contain the version number related to the file.
Try doing a google search for RCS, CVS, and SCCS for more information of Configuration Management tools...
Hope this helps
