Ah, yes. The only advertisment was a post on the mailing list...

We can indeed warn that it's a beta version that will stabilize in the  
next version, just like you did.

I could have remembered and let you know... AFAIR, I checked my  
implementation w/ examples from stats books. Of course, I didn't  
document it at the time and now can't remmbr the details. (Let it be  
an example to younger generations of things not to do...)

Did you put the alias ks_2samp to ks_twosamp, or did I ? Anyway, both  
should work.

Nope, the 2 methods should indeed have the same inputs. Using R's  
might make things easier for people coming from R...

Sounds good, go for it.
