sorry, what i meant is I'll replace all the parts by mBSD style license. > But with what?

I'm also a FreeBSD ports committer, so I'd like to add it for FreeBSD ports tree for easier compilation. > * Some nonsense about GMP (and incidentally no mention of MPIR - note > how many other bignum libraries *are* mentioned). > > * From a code quality point of view, their code looks pretty good to > me, commented well, in english.
