Hi Caolan -

interesting, cool that this is actually possible - I kinda evaded
the full-scale bootstrapping problem somehow, mostly doing 
scaffolding for testing parts of app functionality. There are three 
patches where I ended up with useful unit tests:


The impress autolayout actually gets away w/o any uno setup; the
writer test fakes a uno.ini (see the makefile there) - I guess,
there's a fine line between trying to fake a ~whole office setup,
vs. testing exactly one class (and doing some scaffolding and/or
refactoring to really only test that one class) - for the former,
maybe the complextest framework is a closer fit?

That would be a *very* useful end result.
