How to insert Changelog files automatically

Hello I know that when I use a file which is under version control (say RSC) with the vc backend, I can arrange that the content of the vc log can be inserted in the source file. This can be done by putting something like this %% $Log: free-boundary-beamer.tex,v $ at the file header. Now can this be done, if the file in question is not under version control? (The reason is that for tex file reftex now allows me to locate my changes better, that is reftex would add in which section or close to which equation the change occurred.) So I would like to have something like %% $Log: ChangeLog $ and then every entry into the change log file should be inserted in the source file (best with the adequate comment syntax) Is there any possibility? Thanks Uwe Brauer
