[PATCH wayland v4 4/5] meson: Run Doxygen on the Meson build
Daniel Stone
daniels at collabora.com
Tue Aug 28 22:19:18 UTC 2018
From: Emmanuele Bassi <ebassi at gnome.org>
Add a script which generates the desired Doxygen configuration for our
various output formats and executes it using that configuration.
[daniels: Properly install into mandir/man3 via some gross
paramaterisation, generate real stamp files.]
