I really don't know what to do with git-submodules.

But in this precise case, I would:
  - dump the cal3d package
  - add a post-download hook (or an extra-download URL) to vsxu to also
    download cal3d
  - add a post-extract hook to vsxu to also extract cal3d in the correct
    location.

Then, when/if cal3d is later used by other packages, we can revisit the
situation.

Otherwise, for proper git-submodule handling, we would have to do
(roughly):

    git clone blabla pkg-version
    cd pkg-version
    git checkout pkg-version
    git submodule update --init --recursive
    find . -name .git -exec rm -rf {} +
    cd ..
    tar czf DL_DIR/pkg-version.tar.gz pkg-version/

This is not very complex, but is stil la significant change from our
current git wrapper.

And then, what about svn externals? About Hg subrepos? Does bzr also
have such a thing?

Note that I would not really mind doing such a change. But is it worth
it, given that we currently have only one package that needs submodules?
Or do we have others for which we had to "deal with it" in a crude way?

Yann E. MORIN.
