 Only explicit copyright is from Christof Hoeke, but the mention of Walter
 Doerwald in the credits and the __author__ stanzas in some Python source
 files quite certainly make him a copyright holder.  The upstream licensing
 moved from Creative Commons licensing to LGPL 2.1 and subsequently to LGPL 3.
 Some files such as setup.py mention LGPL 2.1+, but COPYING.LESSER,
 the upstream site, and most files clearly mention LGPL 3+ rendering the
 result LGPL 3+.
