Subject: [PATCH v6 4/9] m4/python: add function to docs_tool.m4 and new m4 module
Date: Mon, 10 May 2021 09:41:00 +0100	[thread overview]
Message-ID: <20210510084105.17108-5-luca.fancellu@arm.com> (raw)
In-Reply-To: <20210510084105.17108-1-luca.fancellu@arm.com>

Add ax_python_module.m4 to have a way to check if
a python module is installed in the system.

Add a function to docs_tool.m4 to throw an error if the
required docs tool is missing.
