Publicité
0. This License applies to any program or other
work which contains a notice placed by the
copyright holder saying it may be distributed
under the terms of this General Public License.
The "Program", below, refers to any such
program or work, and a "work based on the
Program" means either the Program or any
derivative work under copyright law : that is to
say, a work containing the Program or a portion
of it, either verbatim or with modifications and/or
translated into another language. (Hereinafter,
translation is included without limitation in the
term "modification".) Each licensee is addressed
as "you".
Activities other than copying, distribution and
modification are not covered by this License ;
they are outside its scope. The act of running
the Program is not restricted, and the output
from the Program is covered only if its contents
constitute a work based on the Program
(independent of having been made by running
the Program). Whether that is true depends on
what the Program does.
1. You may copy and distribute verbatim copies of
the Program's source code as you receive it, in
any medium, provided that you conspicuously
and appropriately publish on each copy an
appropriate copyright notice and disclaimer of
warranty; keep intact all the notices that refer to
this License and to the absence of any warranty
; and give any other recipients of the Program a
copy of this License along with the Program.
You may charge a fee for the physical act of
transferring a copy, and you may at your option
offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the
Program or any portion of it, thus forming a work
based on the Program, and copy and distribute
such modifications or work under the terms of
Section 1 above, provided that you also meet all
of these conditions :
a) You must cause the modified files to carry
prominent notices stating that you changed
the files and the date of any change.
b) You must cause any work that you distribute
or publish, that in whole or in part contains
or is derived from the Program or any part
thereof, to be licensed as a whole at no
charge to all third parties under the terms of
this License.
c) If the modified program normally reads
commands interactively when run,you must
cause it, when started running for such
interactive use in the most ordinary way, to
print or display an announcement including
an appropriate copyright notice and a notice
that there is no warranty (or else, saying
that you provide a warranty) and that users
may redistribute the program under these
conditions, and telling the user how to view
a copy of this License. (Exception:if the
Program itself is interactive but does not
normally print such an announcement, your
work based on the Program is not required to
print an announcement.)
These requirements apply to the modified work as
a whole. If identifiable sections of that work are not
derived from the Program, and can be reasonably
considered independent and separate works in
themselves, then this License, and its terms, do
not apply to those sections when you distribute
them as separate works. But when you distribute
the same sections as part of a whole which is a
work based on the Program, the distribution of the
whole must be on the terms of this License, whose
permissions for other licensees extend to the entire
whole, and thus to each and every part regardless
of who wrote it.
Thus, it is not the intent of this section to claim
rights or contest your rights to work written entirely
by you ; rather, the intent is to exercise the right
to control the distribution of derivative or collective
works based on the Program. In addition, mere
aggregation of another work not based on the
Program with the Program (or with a work based
on the Program)on a volume of a storage or
distribution medium does not bring the other work
under the scope of this License.
3. You may copy and distribute the Program (or
a work based on it, under Section 2)in object
code or executable form under the terms of
Sections 1 and 2 above provided that you also
do one of the following :
a) Accompany it with the complete
corresponding machine-readable source
code, which must be distributed under
the terms of Sections 1 and 2 above on
a medium customarily used for software
interchange ; or,
b) Accompany it with a written offer, valid for
at least three years, to give any third party,
for a charge no more than your cost of
physically performing source distribution,
a complete machinereadable copy of the
corresponding source code, to be distributed
under the terms of Sections 1 and 2 above
on a medium customarily used for software
interchange ; or,
