Be sure to contact me if you're planning on using it, a lot of features are undocumented (mostly the layout/xml possibilities, I can provide you with some examples but would prefer not to put these online).
Slurf uses Python2.x, doesn't work with Python3.
If you need a build not listed just contact me.
