Changelog inclusion

[Hal Burgiss]

This is probably a dumb question from a new bzr user, but I can't find
this in the documentation and the behavior seems different than cvs.
How does one get the log data included into a bzr managed file. If
memory serves me, in cvs its something like ...

 $Id: $
 $Log:  $

would trigger the revision id and change log data to be included and a
running log would be kept with the file. 

Thanks.
