The FPDoc PDF documentation for 3.0.4 doesn't mention it at all. So
maybe it is something for 3.2.0 and later only?
I'm trying to debug fpdoc, but for the life of me, I can't get Lazarus
to step into the code other than the program unit's main code block. I
set the starting directory, I set the --project=myfile.xml as the run
parameter, but still no luck. I'm running Linux if that matters.
