if this is not the right place to ask, please let me know.
The OTP team is reading here, so I think it's good to
make this a public discussion :)

The CouchDB team is looking at adopting EUnit for
unit testing. Since EUnit is now shipped with OTP since
R12B-5, we're happy to adopt it. Since we are with
the ASF there are some licensing restrictions we need
to take care of. The easiest for us is if we could treat EUnit
as yet another standard OTP library released under the
EPL license.

The R12B-5 source still includes all LGPL boilerplate
and the COPYING file. We understand that this means
that while EUnit ships with OTP, the license remains

Now this discussion took place earlier today:


We're wondering if the LGPL mentions in the source are
mere leftovers or if they are still valid.

In any case, it would be nice to see a definite and
public statement about this that we can link and refer
to in the future. Both readings of the license-possibility
came up in our thread and I am sure we're not the
only ones.
