Because of the disk space demands I think an approach with one 
repository with one branch per CWS would be better for the initial 
import. In hg there are more opportunities for this approach (using 
NamedBranched, UnnamedBranches, MultipleHeads, LocalBranches or 
Bookmarks) than I as git-fan would care to know. Please see the attached 
file where I hacked together a script that imports the CWSs into one 
repository with multiple bookmarks.

As Michael mentioned it's much less than the 250, as only about 15 
CWSses (see for details) are marked as fully tested 
and but not-yet integrated.
 From these the ones targeted at the stabilization branch (calc67, 
calc68, ooo34gsl01, ooo34gsl02, writerfilter10, native373, jl167) are 
more important than the ones targeted for trunk (sb140, sb143, hsqldb19, 
hr77, ause131, sd2gbuild).

There are a few more very good CWSses which were not yet officially 
approved in the old OOo system. E.g. CWS aw080 Armin mentioned. If Armin 
can confirm that this CWS is ready we should pull it in too.

Once we have a better picture of what is ready or not cws-list.txt needs 
to be updated.

Please see the attached file. I'm afraid to check it in as the related is not yet updated accordingly and also because I'm more of 
a HG victim than a HG power-user ;-)

Please note that you either have to use HG>=1.8 or enable its bookmark 
extension before you run the attached script.

Best regards,
