Python click, can you do -h as an alias

Question

I recently found a click library ( http://click.pocoo.org/6/ ) and I like it.

I am trying to figure out if it is possible to create an alias for the --help parameter, which contains help shortcuts. So for example:

 app.py --help

provides assistance for the main application and

 app.py sub --help

will provide assistance for sub. I want to use -h too. If I created this parameter, it might look something like this:

 @click.option('-h', '--help')

but the --help option is built in. Is there a way to expand this setting or create an alias for it?
