[cl-cookbook-contrib] lgpl usage

[Heow Eide-G. <li...@al...>]

An interesting note on the LGPL on common-lisp.net:


What's wrong with LGPL?

Nothing per se, but it probably does not mean what you think it means.
The highly C-centric point of view of the LGPL makes a distinction
between static and dynamic linking, but tells us very little about
certain issues that are of paramount importance for Lisp users:

    * Is loading LGPL code into a non-LGPL image ok? (runtime
dependency)
    * Is it ok to use LGPL macros in non-LGPL code? (compile-time
dependency)
    * Is it ok to redefine operators provided by the LGPL code in
non-LGPL code?
    * Is it ok to distribute an image with LGPL code loaded?

Whether or not these questions are answerable within the bounds of the
LGPL is a matter of debate, but given that the interpretation is not
clear we do not recommend using the LGPL license for Common-lisp.net
projects. If you want to disallow all of the above use GPL, and if you
want to allow some or all of them use LLPGL or MIT/BSD/X11 style
licenses.
