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 modifi ed 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
These requirements apply to the modifi ed work as
a whole. If identifi able 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.
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 modifi cations or work under the terms of
Section 1 above, provided that you also meet all of
these conditions:
a) You must cause the modifi ed fi les to carry
prominent notices stating that you changed the
fi les and the date of any change.
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,
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.
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 machine-readable
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,
c) Accompany it with the information you received
as to the offer to distribute corresponding source
code. (This alternative is allowed only for non-
commercial distribution and only if you received
is interactive but does not normally print such an
announcement, your work based on the Program is
not required to print an announcement.)
the program in object code or executable form with
such an offer, in accord with Subsection b above.)
The source code for a work means the preferred
form of the work for making modifi cations to it. For
an executable work, complete source code means
all the source code for all modules it contains, plus
recipients of the Program a copy of this License
along with the Program.
scripts used to control compilation and installation
of the executable. However, as a special
exception, the source code distributed need not
include anything that is normally distributed (in
either source or binary form) with the major
components (compiler, kernel, and so on) of the
operating system on which the executable runs,
unless that component itself accompanies the
executable.If distribution of executable or object
code is made by offering access to copy from a
designated place, then offering equivalent access
to copy the source code from the same place
counts as distribution of the source code, even
though third parties are not compelled to copy the
source along with the object code.
4. You may not copy, modify, sublicense, or
distribute the Program except as expressly
provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute
the Program is void, and will automatically
terminate your rights under this License. However,
parties who have received copies, or rights, from
you under this License will not have their licenses
terminated so long as such parties remain in full
compliance.
