The code I ported is a standalone library that can be imported into a web page and then its functions can be called. There is a lot of useful code that looks like that. It is a shame that there is no standard bit bucket that you can put it in.
My statement is that having a widely known repository is still useful for random libraries which are simple enough to not have dependencies. I completely agree that having a standard way of loading dependencies would make such a thing much more useful still, but it still has utility without that.
Seriously, if you need to be able to calculate several standard probability distributions to 5 digits of precision in JavaScript, you can do it today with the library that I ported. Either embedded or server side. Doesn't matter. Go ahead and use it. (If GPL/Artistic doesn't work for you then I'm sorry. I can't grant a more generous license than the Perl version I started with.)
