Usage: $ME [OPTIONS] [ARGS]
|
||||
|
||||
Convert git log output to ChangeLog format. If present, any ARGS
|
||||
are passed to "git log". To avoid ARGS being parsed as options to
|
||||
$ME, they may be preceded by '--'.
|
||||
|
||||
OPTIONS:
|
||||
|
||||
--since=DATE convert only the logs since DATE;
|
||||
the default is to convert all log entries.
|
||||
|
||||
--help display this help and exit
|
||||
--version output version information and exit
|
||||
|
||||
EXAMPLE:
|
||||
|
||||
$ME --since=2008-01-01 > ChangeLog
|

$ME -- -n 5 foo > last-5-commits-to-branch-foo
