plugins

[Heitzso]

I just downloaded and setup 0.0.7 bzr then copied
some of the plugins to .bzr.conf/plugins from the web
site (I was wanting a push like command to push my
deltas to a common repository).

When I then run
    bzr plugins
I get the list of pyc files now in my ~/.bzr.conf/plugins
directory.   But no extra commands show up.
    bzr annotate -h
complains that no annotate command exists.
    bzr help
does not show new commands
    bzr push
complains that command not available

    bzr plugins
returns
    /usr/local/src/bzr-0.0.7/bzrlib/plugins/__init__.pyc
        Null placeholder plugin
    /home/heitzso/.bzr.conf/plugins/bzrtools.pyc
    /home/heitzso/.bzr.conf/plugins/conflicts.pyc
    /home/heitzso/.bzr.conf/plugins/push.pyc

??

Also, while the idea of a central repository may be
anathema to the idea of distributed repositories, I
still need to sync my various working systems to a
common (dare I say central) repository without  having
to drag around a usb thumbdrive, etc.  In other words,
I work on a laptop for awhile, then my OSX system,
then my Ubuntu dev box, etc.   I think I understand
the idea of 'pull' (equiv cvs update).  But where's the
push side?  Is that what the tools plugin push is
supposed to do?

Thanks,
