west medicine is good

The GPL was written by Richard Stallman in 1989,
for use with programs released as part of the GNU project. The original GPL was
based on a unification of similar licenses used for early versions of GNU Emacs
(1985), the GNU Debugger, and the GNU C Compiler. These licenses contained similar
provisions to the modern GPL, but were specific to each program, rendering them
incompatible, despite being the same license. Stallman’s goal was to produce one
license that could be used for any project, thus making it possible for many
projects to share code.

The second version of the license, version 2, was released in 1991. Over the
following 15 years, members of the free software community became concerned over
problems in the GPLv2 license that could let someone exploit GPL-licensed software
in ways contrary to the license’s intent. These problems included tivoization (the
inclusion of GPL-licensed software in hardware that refuses to run modified versions
of its software), compatibility issues similar to those of the Affero General Public
License, and patent deals between Microsoft and distributors of free and open-source
software, which some viewed as an attempt to use patents as a weapon against the
free software community.

Version 3 was developed to attempt to address these concerns and was officially
released on 29 June 2007.

Terms and conditions

The terms and conditions of the GPL must be made available to anybody receiving a
copy of the work that has a GPL applied to it (“the licensee”). Any licensee who
adheres to the terms and conditions is given permission to modify the work, as well
as to copy and redistribute the work or any derivative version. The licensee is
allowed to charge a fee for this service, or do this free of charge. This latter
point distinguishes the GPL from software licenses that prohibit commercial
redistribution. The FSF argues that free software should not place restrictions on
commercial use, and the GPL explicitly states that GPL works may be sold at any

The GPL additionally states that a distributor may not impose “further restrictions
on the rights granted by the GPL”. This forbids activities such as distributing of
the software under a non-disclosure agreement or contract.

Communicating and bundling with non-GPL programs

The mere act of communicating with other programs does not, by itself, require all
software to be GPL; nor does distributing GPL software with non-GPL software.
However, minor conditions must be followed that ensures the rights of GPL software
is not restricted. The following is a quote from the gnu.org GPL FAQ, which
describes to what extent software is allowed to communicate with and be bundled with
GPL programs:

An “aggregate” consists of a number of separate programs, distributed
together on the same CD-ROM or other media. The GPL permits you to create and
distribute an aggregate, even when the licenses of the other software are
non-free or GPL-incompatible. The only condition is that you cannot release the
aggregate under a license that prohibits users from exercising rights that each
program’s individual license would grant them.

The FSF thus draws the line between “library” and “other program” via 1) “complexity”
and “intimacy” of information exchange, and 2) mechanism (rather than semantics),
but resigns that the question is not clear-cut and that in complex situations, case
law will decide.

Compatibility and multi-licensing

Code licensed under several other licenses can be combined with a program under the
GPL without conflict, as long as the combination of restrictions on the work as a
whole does not put any additional restrictions beyond what GPL allows. In addition
to the regular terms of the GPL, there are additional restrictions and permissions
one can apply:

  1. If a user wants to combine code licensed under different versions of GPL, then
    this is only allowed if the code with the earlier GPL version includes an “or
    any later version” statement. For instance, the GPLv3 licensed GNU LibreDWG
    library can’t be used anymore by LibreCAD and FreeCAD who have GPLv2 only
  2. Code licensed under LGPL is permitted to be linked with any other code no matter
    what license that code has, though the LGPL does add additional requirements for
    the combined work. LGPLv3 and GPLv2-only can thus commonly not be linked, as the
    combined Code work would add additional LGPLv3 requirements on top of the
    GPLv2-only licensed software. Code licensed under LGPLv2.x without the “any
    later version” statement can be relicensed if the whole combined work is
    licensed to GPLv2 or GPLv3.

FSF maintains a list of GPL-compatible free software licenses containing many of the
most common free software licenses, such as the original MIT/X license, the BSD
license (in its current 3-clause form), and the Artistic License 2.0.
