recent CVS updates (plus: new FTP snapshots)

Folks, here's a thumbnail sketch of Arusha stuff that's
changed in CVS land, which hasn't been mentioned before.

* Bugs are still being fixed in the ARK engine
  (ARK/arkbase/) after the misnamed "ARK2" switch.  I expect
  this to continue :-(

* Unit testing stuff for said engine is slowly taking shape
  in ARK/arkbase/ark/*tests.py.  I also expect this to
  continue (hooray!).

* I've tried to do good things with the ArkHost.run(...)
  method [it runs some code on a host], but have mostly
  failed; I'll send a separate message about this...

* I made a sidaiTemplatePerHost method (sorry, Jonathan),
  that parallels sidaiM4perHost().  (I want to lose most of
  the m4 stuff.)

* We now have the new-and-totally up-to-date 'ersh' script
  (v 4.0) from Maarten Litmaath.

* Matt has done some Very Cool stuff with sidai/user-setup/
  (a way of having site-wide .profile/.cshrc/.emacs etc).
  Instead of having to maintain parallel sets of bits for
  bourne/c-shell users, he's got a cool hack that lets you
  say it just once; see the common.* files...
  (Now we just need common.compctl [completion control] :-)

* The usual march of progress with installing more packages
  that do more stuff.

Please holler if there's anything you want to know more
about.

Snapshots in ftp://ark.sourceforge.net/pub/ark; I'm not
refreshing the web pages at this time.
