Doug Davis 8324d7918b Carry #11858 Continues 11858 by: - Making sure the exit code is always zero when we ask for help - Making sure the exit code isn't zero when we print help on error cases - Making sure both short and long usage go to the same stream (stdout vs stderr) - Making sure all docker commands support --help - Test that all cmds send --help to stdout, exit code 0, show full usage, no blank lines at end - Test that all cmds (that support it) show short usage on bad arg to stderr, no blank line at end - Test that all cmds complain about a bad option, no blank line at end - Test that docker (w/o subcmd) does the same stuff mentioned above properly Signed-off-by: Doug Davis <dug@us.ibm.com>		2015-05-23 09:14:18 -07:00

Package mflag (aka multiple-flag) implements command-line flag parsing.
It's an hacky fork of the official golang package

It adds:

$>./example -h
Usage of example:
  -s, --string="": a simple string

It is very flexible on purpose, so you can do things like:

$>./example -h
Usage of example:
  -s, -string, --string="": a simple string

Or:

$>./example -h
Usage of example:
  -oldflag, --newflag="": a simple string

You can also hide some flags from the usage, so if we want only --newflag:

$>./example -h
Usage of example:
  --newflag="": a simple string
$>./example -oldflag str
str

See example.go for more details.
