Use commit message from file
In the proces of cleaning and migrating a large set of SVN repositories I would put a file in the root of a repository to indicate the status of the repository. These files would either be called:
Indicating the state of the code in the repository.
The file would contain a brief message, with an explanation and with a link to the new repository if migrated.
Often I would find myself echoing the same information into the log message, until it struck me that there had to be a better (faster) way of doing this and it appears that SVN supports this
$ svn add MIGRATED $ svn commit --force-log -F MIGRATED MIGRATED
Please note the
--force-log, which has to be used because the file is under revision control.
