Usage: $ME [OPTIONS] [ARGS]
57
Convert git log output to ChangeLog format. If present, any ARGS
58
are passed to "git log". To avoid ARGS being parsed as options to
59
$ME, they may be preceded by '--'.
63
--since=DATE convert only the logs since DATE;
64
the default is to convert all log entries.
65
--format=FMT set format string for commit subject and body;
66
see 'man git-log' for the list of format metacharacters;
67
the default is '%s%n%b%n'
69
--help display this help and exit

--version output version information and exit
