From bd06b648fb1c7b0a137f23f15cd5e72c5edd881a Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Mon, 24 May 2021 16:46:42 +0900 Subject: utils: ipc: Add script to extract doxygen docs from mojom files Add a script to extract doxygen documentation comments from mojom files. It matches based on ^\/\*\*$ for start of block and ^ \*\/$ for end of block, and simply copies the comments to the output file along with a header and the libcamera namespace. Also add it to the meson file so it is usable by other meson files.
