Did not know that. I am game to move the Math packages over there. Since around 2005 I've been using DVCS, first bazaar and for the last couple of years, git, and really going to svn feels like a step back (it is just my own opinion).

Will take a look at that during the following week and push that to svn just for completeness (after I push that to github) > While I am at it and being innnnnncreadibly annoying here, sorry for that, > would you consider moving the code away from PHP License to say...

Actually I do like the New BSD better (just because I am partial to the old Unix ways). That is clearly doable and just a quick sed/awk job.

I'd rather those are fixed on the ...2 versions, which also gives a chance to improve the design. Hindsight is always 20-20 and there were some design decisions that could've been better..
