Looks like this is modified version of q3map2 for Quake. Thus, probably it's not a good way to package with the same name. From other side, q3map2 for xonotic is not distributed separately from xonotic source (it's in http://dl.xonotic.org/xonotic-0.7.0-mappingsupport.zip) and looks like it must be compiled within whole xonotic repository (xonotic/netradiant.git). Therefore, maybe q3map2 should be a part of other xonotic package.
