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 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 noncommercial
distribution and only if you received 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 modifications to it.
For an executable work, complete source code
means all the source code for all modules it
contains, plus any associated interface definition
files, plus the 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
