[mdz@canonical.com: Bug#285745: Completion for baz]

[Clint Adams]

I imagine that some stuff could be factored out of _tla, _baz, and
_larch (well, _larch looks like it needs to be finished before it will
have anything in common), but I'm committing as-is for now.

Re: [mdz@canonical.com: Bug#285745: Completion for baz]

[Felix Rosencrantz]

What is baz?  Some quick web searches didn't really turn anything up.

It sounds like it is an offshoot of Tom Lord's Arch.  The _larch
completion was something I generated based on the help output from the
Tom Lord's arch tool back in 2002.   It looks like _tla might be the
better completion function for arch now.  It was added in 2004.  So it
seems like _larch should be removed from the distribution. It's large,
and doesn't seem like it would be used by folks. (correct me if I'm
wrong)

I'm not too familiar arch, and any offshoots. So if tla, larch, and 
baz are all different flavors of arch, it would make sense to somehow
combine then. If there are a bunch of flavors of this tool, it would
be nice if someone could give a good pointer.

-FR.

I believe that it is the binary name of the software described at
http://bazaar.canonical.com/ .  I've never used it.

larch was the original implementation of Arch, thusly named because
there's already an 'arch' binary present on most systems.  It was a
shell script and some C programs reimplementing FTP and whatnot.  I've
never used it.

It looks as though baz is diverging from tla in terms of UI as well as
archive format.  ArX ( http://www.nongnu.org/arx/ ), which I have also
never used, is a fork of tla that I believe is completely incompatible
by this point.  I believe that there have been other Arch forks and
reimplementations, but I can't think of any of their names.

Canonical guys should feel free to correct me on any of this.

Yup.

larch is a) known buggy, b) not supported upstream, c) superseded - tla
(& anything branched from it) is a superset of larch functionality.

They are roughly the same, but there are some key differences - for
starters the UI's are quite different, and that gap is growing as we
overhaul the UI in baz. There may be model changes in the future -
though we do want to minimise those. I'm quite happy if the completions
are merged... but baz is a moving target (monthly releases...).

Bazaar has a very strong UI focus, but is also has a custom archive
format that we hope will enable greater flexability in time. We are
talking with upstream (tla) in the hopes that they will adopt what we do
(or a lookalike :)).
