[Openmcl-devel] OpenMCL now LLGPL'ed

I asked Hazem Sayed (president of Digitool, the original copyright holder
of much of the OpenMCL source code) if he had any objection to licencing
OpenMCL under the terms of the "LLGPL" (instead of the LGPL), and he
said that he had no objection.

The LLGPL is a preamble to the GNU Lesser General Public License
(LGPL), which was developed by Franz Inc to clarify how the LGPL
applies to Lisp programs and to amend certain LGPL requirements.
Notably, the LLGPL waives the LGPL requirement that applications be
distributed in a form that would allow the end user to "link to" newer
interface-compatible versions of the "library"; this requirement
would seemingly force developers to distribute their applications
in some sub-optimal format (e.g., as a set of FASL files or something ...)

Franz used that preamble in licensing their AllegroServe product; see


I'll try to add a copy of that preamble (with appropriate global
substitutions) to the OpenMCL distribution ASAP and will look into
whatever else may need to be done to clarify that that preamble
now applies to OpenMCL.
