Subject Re: [math] Random generator
Date Mon, 16 Aug 2004 02:20:13 GMT
This kinda brings us back full circle, I remember back when we started 
talking with Paul Houle about possibly donating the RngPack codebase to 
Math. He had agreed on some levels, but we never approached Licensing 
with all the legal issues. Mostly, he relicensed the entire thing under 
a BSD style license and said he'd be glad to relicense it under apache 
if necessary. But I don't think he was motivated to push this through, I 
think its something we would have to take responsibility for working out 
the details of.
