Port category

I'm almost done porting NsCDE (https://github.com/NsCDE/NsCDE). I'm unsure what category to put it under, however?

It's a "modern" re-implementation of CDE, which is under x11. However, NsCDE really just is a bunch of scripts based on fvwm2. I originally thought about placing it under x11-wm. After mulling it over, I'm uncertain whether this really counts as "window manager" and I should stick with x11?
Would appreciate some feedback, before I put it in a ticket.
But NsCDE doesn't seems to be a DE, it's more like a "fvwm2 configuration to make fvwm2 looks like a CDE" so it'll be more plausible to be at x11-wm.
