[tex-live] pretest=go

[Karl Berry]

Last night's build included the hopefully-final paper size hacking (many
thanks to Norbert and Joseph) and more signature hacking (Norbert
again).  So, I hereby declare the pretest officially open for business,
with thanks to everyone who has already been trying the pre-pretest :).

The binaries are surely not 100% final, but should be close.  I'm not
aware of any specific stoppers or pending changes at this time.  (Not
all platforms are updated yet.)  There will be at least one more build
of the binaries, but they're certainly worth trying now.  This includes
asymptote.

The pdftex, xetex, and TeX Live guide documentation have not been
updated yet, among others.  I hope all that will converge fairly soon.

Regular updates from CTAN will continue (into the pretest) for another
few weeks.

Good luck to us all,
Karl
