The history file
================

   The file `$CVSROOT/CVSROOT/history' is used to log information for
the `history' command (see history.).  This file must be created to
turn on logging.  This is done automatically if the `cvs init' command
is used to set up the repository (see Creating a repository.).

   The file format of the `history' file is documented only in comments
in the CVS source code, but generally programs should use the `cvs
history' command to access it anyway, in case the format changes with
future releases of CVS.
