Why can't you reorganize the layout? If you are using the same components for
multiple projects, you might want to move the common parts to a separate
directory that can be pulled in with an external reference by the things that
need it. Or maybe you can just let the extra files get pulled into the working
copy and make your processing ignore them. Other than the initial copy into the
working copy there shouldn't be much overhead as subsequent updates/commits
ignore unchanged files.
