Usage: $ME [OPTION]... [ <REVIEWER> ]...
Options:
-a ask for Bug ID addition. This option is set by default for
non 'master' branches.
-b BRANCH use BRANCH to submitting patch. Default branch is 'master'.
-d dry run. Show what command to run.
-n do not fetch origin.
-t TOPIC use TOPIC to submitting patch.
-h display this help text and exit.
By default, BUGID is used as topic in patch submission. If TOPIC and
BUGID are used together, TOPIC gets used.
Examples:
# submit patch to master branch without reviewer
$ $ME
# submit patch to master branch with reviewer
$ $ME charlie@example.com
# submit patch to release-3.0 branch with topic "awesome feature" and
# reviewers charlie@example.com alice@example.com
$ $ME -b release-3.0 -t "awesome feature" charlie@example.com alice@example.com
