Sorry for messing things up.

I would have loved if you would have given a link to some newer togl
version 2.1 (I can not find it neither the netgen version you are
mentioning).  That would have been more productive than links to
BestPractices - simply assume that the target audience of your mail
knows about transitions.

We have the following situation

  togl 1.7 (released 2006) was never uploaded since 2010
  togl 2.0 (released 2008) had several commits in SVN which I now
                           uploaded when doing the Git migration and
                           fixing most of the open bugs.

If we use this accident of mine (I admit - an upload to experimental
would have been better) to upgrade way outdated netgen to some recent
version that would be some positive outcome.

My suggestion would be to upgrade netgen to a version that works with
latest togl.

If it is not possible to port xcrysden maintaining a togl1 package could
be an option - but only if we can *really* maintain it.

Kind regards

        Andreas.
