So basically you work out a built product version number based on the
current subversion revision number and path (as obtained by running
'svn info' within the build process).

This approach could work, although I think it would be nice to have the
process a bit more defined in the build step configuration rather than
in external scripts.

I guess it would be nice if you could evaluate build steps conditionally
based on the branch, and it would be also nice if you could pass some of
the branch, revision and 'try' state through to the build steps instead
of having them run 'svn info' to try and figure it out.
