Exceptions
----------

As a special exception, some parts of emx can be distributed without
source code if and only if the code has not been modified and a notice
is included where the source code can be obtained.  This special
exception applies to the following files:

  \emx\bin\emx.exe
  \emx\bin\emxd.exe
  \emx\dll\emx.dll
  \emx\dll\emxio.dll

When distributing modified copies of those files, the GPL applies
without exceptions and you have to remove all references to this
exception from the source code and the documentation.  You must not
change the existing Copyright notice.  If you modify a source file, a
notice to that effect must be added to the source file.

As a special exception, if you bind emxl.exe or emx.exe to an
executable file (using emxbind), this does not cause the resulting
executable file to be covered by the GNU General Public License.  This
exception does not however invalidate any other reasons why the
executable file might be covered by the GNU General Public License.
However, if you bind a modified copy of emxl.exe or emx.exe to
an executable file (using emxbind), you have to include source code
for emxl.exe or emx.exe, respectively.

The emx libraries are not distributed under the GPL.  Linking an
application with the emx libraries does not cause the executable to be
covered by the GNU General Public License.  You are allowed to change
and copy the emx library sources if you keep the copyright message
intact.  If you improve the emx libraries, please send your
enhancements to the emx author (you should copyright your enhancements
similar to the existing emx libraries).  Of course, all this does not
apply to the libraries which are distributed under the GPL or the GNU
Library General Public License (LGPL, see \emx\doc\COPYING.LIB) or the
BSD license (see \emx\doc\COPYING.BSD), such as termcap.a, gpp.a and
curses.a.

Code derived from code released by the University of California,
Berkeley, is released under the terms of \emx\doc\COPYING.BSD.  This
applies to the libraries `bsd', `btermcap', `curses', and `db'.

There is also a special exception for the GNU standard C++ library,
libstdc++, see \emx\doc\COPYING.SCP.  This applies to stdcpp.a and
stdcpp.lib.

You are allowed to use, copy, and change the programs in \emx\sample
if you keep the copyright message intact.  The test programs in
\emx\test are in the public domain.

Permission is granted to make and distribute verbatim copies of the
manuals written by Eberhard Mattes provided the copyright notice is
preserved on all copies.  If you modify those manuals, a notice to
that effect must be added to the manual.


Summary
-------

1. Redistributing emx and GNU programs

  If you redistribute emx and the GNU programs, you also have to
  redistribute the source code:

    emxdev1.zip, emxdev2.zip  ->  emxsrcd1.zip, emxsrcd2.zip
    emxrt.zip                 ->  emxsrcr.zip
    gnudev1.zip, gnudev2.zip  ->  gccsrc1.zip, gccsrc2.zip, gccsrc3.zip,
                                  gdbsrc1.zip, gdbsrc2.zip, gnusrc.zip,
                                  gbinusrc.zip
    gnuinfo.zip               ->  gnusrc.zip
    gppdev.zip                ->  gppsrc.zip, gccsrc1.zip, gccsrc2.zip,
                                  gccsrc3.zip
    gobjcdev.zip              ->  gccsrc1.zip, gccsrc2.zip, gccsrc3.zip

2. Distributing applications

  There are no copyright restrictions on applications created with the
  emx tools and the GNU C compiler and linked with the emx libraries.
  However, there are restrictions for applications linked with GNU or
  BSD libraries.

3. Distributing the emx runtime package

  If you distribute emxrt.zip, you also have to redistribute
  emxsrcr.zip.  If you electronically distribute an application which
  requires the emx runtime package, I recommend putting a pointer to
  emxrt.zip into the documentation instead of distributing emxrt.zip.
  That way, users usually get the latest version of emxrt.zip.

4. Distributing applications and emx.dll, emxio.dll and emx.exe

  For small programs, redistributing emxrt.zip may be inconvenient.
  You are allowed to distribute emx.dll, emxio.dll, and emx.exe with
  your application as long as emx.dll, emxio.dll, and emx.exe have not
  been modified.  You should include a notice in the documentation
  which tells users where they can get the complete emx package.

  Note that you can create stand-alone OS/2 applications (using the
  -Zomf -Zsys options of GCC) which do not need emx.dll.

5. Distributing modified copies

  If you modify an emx tool, the GPL will apply without exception,
  that is, you have to include full source code.  See COPYING for
  details.  If you distribute a modified emx.dll, please choose
  another name for the DLL to avoid compatibility problems.  For
  instance, if someone adds feature A to emx.dll, and someone else
  adds feature B to emx.dll, programs using feature A cannot be run
  simultaneously with programs using feature B because only one
  instance of any DLL can be active (either feature A or feature B
  will be present, but not both).  If the DLLs are named emx_a.dll and
  emx_b.dll, that problem does not arise.  The -E option of emxbind
  selects the name of the emx DLL to use.
