I don't know about Jardrup's tools (I need to take a look), but I'm pretty sure qflight doesn't do sunlight. Beyond keeping things maybe working, qflight and qfvis have been mostly neglected. Even qfbsp to a certain extent

Only one of me and too much code. It's got me surrounded. All those files are out to get me. No fair, several hundred to one. Help, help, I'm drowning in code.
Just kidding, but there is only one of me and a huge todo list. A pointer to his code would be fantastic.
qfbsp
does support detail, hint and skip brushes/faces. And entity origin (for rotation), it seems. qflight does have some extensions, but I've lost track of what. The worst bit is other than a brief look (and a bit of a fight with pthreads in qfvis), I haven't really touched much of that code since 2004 or earlier, though I did put doxygen comments on just about every qfbsp function.
