including an appropriate copyright
notice and a notice that there

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

announcement, your work based
on the Program is not r

These requirements apply to the
modied work as a whole. If identiable
sections of that work are not derived
from the Pr
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 par
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 no
with the Program (
on the Program) on a v
storage or distribution medium does
not bring the other work under the
scope of this License.

Program (
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) A
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 oer

copy of the corresponding source

c) A

distribution and only if you

b above.)
The source code for a work means the
preferred f
modications to it. For an ex
work, complete source code means
all the source code for all modules it
contains, plus any associated interface
denition les, plus the scripts used to
control compilation and installation
of the executable. However
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
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 oering access t
from a designated place, then o
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.

expressly provided under this License.
Any attempt otherwise to copy, modify
sublicense or distribute the Program is

will not have their licenses terminated
so long as such parties remain in full
compliance.
