[ANNOUNCE] svkup preview

I've just put svkup and svkupd to the branch at
svn://svn.clkao.org/svk/branches/svkup.

It should probably be a separate dist, but for now it will be easier
to test and hack this way.

svkup (you may want to pronounce it as suck-up) is designed for
software distribution in a distributed manner, for users who don't
need to commit from the machine. This is pretty much like what cvsup
do, but it should be a lot faster since it's no longer file based..

You specify a resource "<uuid>:<path>" you want to get. svkupd server
is SVN::Mirror-aware, you can switch to another server that has the
mirror of the same resource the next time you run svkup. (Ok, it's
not quite true yet, the translation of revision back to the one on the
master repository is not done.)

To run the server:

  perl -Ilib bin/svkupd --depot /path/to/repository

And the client:

  perl -Ilib bin/svkup localhost /path/to/checkout <uuid>:<path>

the next time you can just run :

  perl -Ilib bin/svkup localhost /path/to/checkout

It's still in very early stage, a lot of things have to be done. See
todo section in bin/svkup.

Cheers,
