Would this be appropiate way to list all contributos, and/or perhaps there are more?
They could be listed on the top of each file, after the license text.

Currently the library contains the following licenses:

• GNU Lesser General Public 2.1

• Apache License, Version 2.0

The latter license is used only in few files, LGPL in many places. Some files have neither.
Should we move to GPL v3?
Any comments...
