which mix-ins or USE flags should be set for WM Awesome?

[freefog]

Hi another new Funtoo  user here :

https://www.funtoo.org/Package:Awesome_(Window_Manager) for KDE Funtoo has the kde mix-in and in Gentoo's wiki they recommend gnome, doc, dbus, luajit USE flags , I was wondering :

Q1 - Is there an equivalent or recommended mix-in for this or other Windows Managers? X?

Q2 - I don't understand why they recommend gnome and dbus as a USE flags for this app.

Q3 - I'm mostly interested in seting luajit flag. a) Does Funtoo support it? ; b) How do I check this on my own so I don't bother anyone? ; c) is there a way to see which flags a package is using, really using and not just theoretical? ; d) Can I use /etc/portage/package.use as a directory with different files inside for each package or in Funtoo package.use is always a file?.

Thanks for your time.
