MPFR C++ Free and Open Source Software ("FOSS") License Exception

What is the FOSS License Exception?

MPFR C++ Free and Open Source Software ("FOSS") License Exception allows
developers of FOSS applications to include the Pavel Holoborodko's MPFR C++
Interface with their FOSS applications. The MPFR C++ Interface is typically
licensed pursuant to version 3 of the General Public License (GPL), but this
exception permits distribution of the MPFR C++ Interface with a developer's
FOSS applications licensed under the terms of another FOSS license listed
below, even though such other FOSS license may be incompatible with the GPL.

The following terms and conditions describe the circumstances under which
Pavel Holoborodko's MPFR C++ FOSS License Exception applies.


MPFR C++ FOSS License Exception Terms and Conditions

1. Definitions.
  "Derivative Work" means a derivative work, as defined under applicable
     copyright law, formed entirely from the Program and one or more FOSS
		 Applications.
  "FOSS Application" means a free and open source software application
     distributed subject to a license listed in the section below titled
     "FOSS License List."
  "FOSS Notice" means a notice placed by Pavel
     Holoborodko in a copy of the MPFR C++ Interface stating that such
     copy of the MPFR C++ Interface may be distributed under MPFR C++
     FOSS License Exception.
  "Independent Work" means portions of the Derivative Work that are not
	   derived from the Program and can reasonably be considered independent
     and separate works.
  "Program" means a copy of Pavel Holoborodko's MPFR C++ Interface that
     contains a FOSS Notice.

2. A FOSS application developer ("you" or "your") may distribute a Derivative
 Work provided that you and the Derivative Work meet all of the following
 conditions:
 a.You obey the GPL in all respects for the Program and all portions (including
   modifications) of the Program included in the Derivative Work (provided that
   this condition does not apply to Independent Works);
 b.The Derivative Work does not include any work licensed under the GPL other
   than the Program;
 c.You distribute Independent Works subject to a license listed in the section
   below titled "FOSS License List";
 d.You distribute Independent Works in object code or executable form with the
   complete corresponding machine-readable source code on the same medium and
   under the same FOSS license applying to the object code or executable forms;
 e.All works that are aggregated with the Program or the Derivative Work on a
   medium or volume of storage are not derivative works of the Program, Derivative
   Work or FOSS Application, and must reasonably be considered independent and
   separate works.

3. Pavel Holoborodko reserves all rights not expressly granted in these terms
 and conditions. If all of the above conditions are not met, then this FOSS
 License Exception does not apply to you or your Derivative Work.


FOSS License List

License Name                          Version(s)/Copyright Date

When an Independent Work is licensed under a "Compatible License" pursuant to
the EUPL, the Compatible License rather than the EUPL is the applicable license
for purposes of these FOSS License Exception Terms and Conditions.


FAQ
Q1: What are the benefits of the FOSS License Exception?
A: The FOSS License Exception permits use of the GPL-licensed MPFR C++
 Interface with software applications licensed under certain other FOSS
 licenses without causing the entire derivative work to be subject to the GPL.

Q2: Can commercial OEMs, ISVs or VARs combine and distribute commercial
 products with Pavel Holoborodko's GPL-licensed MPFR C++ Interface under
 the FOSS License Exception?
A: Distributors of commercial products that combine the GPL-licensed MPFR C++
 Interface with commercially licensed software (i.e., software not licensed
 under a FOSS license) must comply with the terms of the GPL. The FOSS License
 Exception does not apply with respect to products licensed under any license
 other than the FOSS licenses listed in the section above titled "FOSS License
 List".
 Non-free licenses may also be purchased from Pavel Holoborodko by application
 developers who do not want their derivative work licensed under the terms of
 the GPL or any FOSS licenses listed in the section above titled "FOSS License
 List".

Q3: What should a developer of a Derivative Work do if it wants to distribute
 the Derivative Work under the GPL?
A: A developer may choose to distribute a copy of a Derivative Work exclusively
 under the terms of the GPL at any time by removing the FOSS License Exception
 notice from that copy of the Program and including appropriate GPL notices.

Q4: If I have more questions, who should I contact?
A: For more information, please contact Pavel Holoborodko <pavel@holoborodko.com>.
