how to add local changes to buildworld?

[Daniel Braniss]

Hi,
I have some local additions which int the past, after making changes to some Makefiles, etc, I got them compiled
but somehow, things stopped working after 11, so I’m now trying to do a fresh set of patches,
and was wondering if there is some docs around on how to to this cleanly? trying to figure out the *.mk is becoming a bit complicated.
thanks,
