I don't agree with Ian's new restrictions on the DFSG and I don't
like turning it into a legal document.
I would like to propose instead the following text, which is the
existing DFSG, verbatim, with a short new preamble and some
exceptions at the end.
Debian Free Software Guidelines
These are the guidelines which packages must satisfy in order to
be included in Debian's main distribution. This is not a legal
text; packages must comply with the spirit of these guidelines,
not just the letter.
1. Free Redistribution
The license of a Debian component may not restrict any party from
selling or giving away the software as a component of an aggregate
software distribution containing programs from several different
sources. The license may not require a royalty or other fee for such
2. Source Code
The program must include source code, and must allow distribution in
source code as well as compiled form.
3. Derived Works
The license must allow modifications and derived works, and must allow
them to be distributed under the same terms as the license of the
4. Integrity of The Author's Source Code
The license may restrict source-code from being distributed in modified
form _only if the license allows the distribution of "patch files" with
the source code for the purpose of modifying the program at build time.
The license must explicitly permit distribution of software built from
modified source code. The license may require derived works to carry a
different name or version number from the original software. (This is a
compromise. The Debian group encourages all authors to not restrict any
files, source or binary, from being modified.)
5. No Discrimination Against Persons or Groups
The license must not discriminate against any person or group of
6. No Discrimination Against Fields of Endeavor
The license must not restrict anyone from making use of the program in
a specific field of endeavor. For example, it may not restrict the
program from being used in a business, or from being used for genetic
7. Distribution of License
The rights attached to the program must apply to all to whom the
program is redistributed without the need for execution of an
additional license by those parties.
8. License Must Not Be Specific to Debian
The rights attached to the program must not depend on the program's
being part of a Debian system. If the program is extracted from Debian
and used or distributed without Debian but otherwise within the terms
of the program's license, all parties to whom the program is
redistributed should have the same rights as those that are granted in
conjunction with the Debian system.
9. License Must Not Contaminate Other Software
The license must not place restrictions on other software that is
distributed along with the licensed software. For example, the license
must not insist that all other programs distributed on the same medium
must be free software.
10. Example Licenses
The "GPL", "BSD", and "Artistic" licenses are examples of licenses that
we consider "free".
Documentation must be modifiable in the same way as software.
The licence of a Standard may prohibit alteration of the text. However,
it must allow the text to be copied and altered so long as the result
does not pretend to be the Standard it was copied from.
The licence of works of information or reference must allow them to
Literary works or artistic images may be licensed under terms that
prohibit their being altered, so long as they may be freely
National restrictions and patents
The existence in certain countries of legislation or patents that
restrict rights to use or distribute a package do not mean that
that package is not regarded as free, even if those restrictions
mean that it is not practicable to include the package in the main
