Sure, and it's called `update'.  :-)  To summarize:

  # Teach tla that some archive (or ``repository'') is available at URI.
  $ tla register-archive URI

  # At this point, it knows that an archive named
  # `blah@blah.org--SOME-ARCHIVE' is available at URI.
  # From now on, you will always use this name and not the URI.

  # You can now get files from that archive.

  $ tla get blah@blah.org--SOME-ARCHIVE/C--B--V  DIR
  # This retrieves the latest version of the branch C--B--V into
  # directory DIR.

  $ cd DIR

  # Updating the local copy, as with `cvs update':
  $ tla update

It's not all that complicated.  All you need is to be aware of certain
conventions, some of which are, well, quite unusual (some might say
``weird'').  ;-) Most importantly, you need to know that
``repositories'' are usually called ``archives'', and that a particular
naming scheme is enforced for branch names, namely
CATEGORY--BRANCH--VERSION.  And yes, conventions in GNU Arch are a
controversial topic.

More information is available in the (slightly outdated) tutorial:
http://www.gnu.org/software/gnu-arch/tutorial/arch.html .

Thanks,
Ludovic.
