[Rivet] Bootstrap update

[Andy Buckley]

Hi all,

I just spent a fun couple of hours replacing our hyper-complicated
Python bootstrap script with.... yes, a much more stupid shell script.
Or rather, two of them: one for Rivet 1.x, the other for 2.x.

There's no longer a command line UI, and it doesn't attempt to deal with
every config scenario under the sun (including semi-contradictory ones).
That's how we got into the mess of supporting such a complex script in
the first place, and at least I would rather be doing physics than
supporting a script just intended to help people without access to CERN
AFS to get started. The first few lines in the script are hopefully
self-explanatory and can be edited to change the configuration, in the
good ol' "theory code" fashion. In fact, the whole script is probably
more easily read and edited than the previous dump from --help.

The new scripts also don't do bootstrapping from version control, i.e.
for developers. Tarballs only, please. If you want to do development, I
hope you know enough to build a few dependency packages, and for testing
pre-release builds we can easily make and update beta / release
candidate tarballs in the Rivet download area. You _can_ convince me
otherwise -- we'll need an extra rivet-dev-bootstrap script which will
be 80% the same but also has to install Cython, check that hg exists,
call autoreconf -i, etc. -- but it'd better be a good argument ;-)

I'll update the web docs re. bootstrapping and analysis migration from
AIDA to YODA tomorrow... and then get started on integrating the latest
analyses for 1.8.4 and 2.0.1. It's good to be moving again :-D

Andy
