Options
-------

.. option:: ShortNamespaceLines

   Requires the closing brace of the namespace definition to be followed by a
   closing comment if the body of the namespace has more than
   `ShortNamespaceLines` lines of code. The value is an unsigned integer that
   defaults to `1U`.

.. option:: SpacesBeforeComments

   An unsigned integer specifying the number of spaces before the comment
   closing a namespace definition. Default is `1U`.

.. option:: AllowOmittingNamespaceComments

   When `true`, the check will accept if no namespace comment is present.
   The check will only fail if the specified namespace comment is different
   than expected. Default is `false`.
