The author(s) of the GPL code, I dont know who the authors of this
code are. But baptiste is likely one


find a version of this code that is LGPL, it was hinted at in the
thread that a version from the BBC would exist that is.
Note of course that this may be older and have issues which are
fixed in the GPL code.


Seperate the code in such a way that its not included unless
--enable-gpl is used during configure


rewrite it without using any of the GPL code

New school: Use the highest level language in which the latest supercomputer
