It is free even for commercial use and includes complete sources.
I would emphasize that this really is an alpha. It has had virtually no

for getting real work done.
If you find bugs, please be sure to report them. If you find what seems
to be a really blatant, crippling bug don't assume that you must be
doing something wrong and don't assume somebody else will have reported
it.
