So what do you recommend as the default path? To me this seems a lot
like a 'compiled in default' that other programs use. So you pass it as
a parameter to the 'configure' script.

Bzr doesn't really have the same 'configure' step that other programs have.

I suppose one possibility would be 'bzrplugins' so something like
/usr/lib/python2.4/site-packages/bzrplugins

which sits *next* to bzrlib rather than underneath it.

Then at runtime we find it by just running 'import bzrplugins; path =
dirname(bzrplugins.__file__)' or something like that.

Thoughts?
