It is better to have docs built in the repo so that building scm version doesn't fail with 'missing doc directory' error.

Mutually exclusive groups
|
|
=========================
|
|
|
|
A group of options can be marked as mutually exclusive using ``:mutex(option, ...)`` method of the Parser class.
|
|
|
|
.. code-block:: lua
|
|
:linenos:
|
|
|
|
parser:mutex(
|
|
parser:flag "-q --quiet",
|
|
parser:flag "-v --verbose"
|
|
)
|
|
|
|
If more than one element of a mutually exclusive group is used, an error is raised.
