So it sounds like we have at least 3 people quite familiar with
ClearCase. Knowledge of tool X is actually more important than Bazaar
knowledge when writing these docs because they *must* be written from
the perspective of an existing tool X user.

Would someone like to have a go at fleshing out some common ClearCase
tasks and how they think they are done in Bazaar. Don't worry about
being wrong: I'm sure the others will let you know (politely) how to do
things differently if appropriate. :-)

Here's the template to use:
http://doc.bazaar-vcs.org/migration/en/_sources/survival/bzr-for-cleartool-users.txt.
A crash course in ReST formatting can be found here:
http://sphinx.pocoo.org/rest.html.

It is. We could do with some more docs on server admin though as the
recently discussions re bzr_access and backups have shown.

Cool. Right now, I believe the best way of migrating is via Subversion.
It would be really nice to get a clearcase-fast-export tool written some
day!
