svnadmin setlog
Name
svnadmin setlog — Set the log message on a revision.
Synopsis
svnadmin setlog REPOS_PATH -r REVISION FILE
Description
Set the log message on
        revision REVISION to the
        contents of FILE.
This is similar to using svn propset
        with the --revprop option to set the svn:log property
        on a revision, except that you can also use the option
        --bypass-hooks to avoid running any pre-
        or post-commit hooks, which is useful if the modification
        of revision properties has not been enabled in
        the pre-revprop-change hook.
		Warning
	
Revision properties are not under version control, so this command will permanently overwrite the previous log message.
