c) Ifthe 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 anotice that there
is
no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program
underthese conditions, and telling the user how to
view acopy
of
this License, (Exception: ifthe 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
awhole, Ifidentifiable 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 ofawhole which
is
awork based on
the Program, the distribution ofthe 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 ofwho 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
ofphysically
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
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,
5.
You
are
not
required
to
accept
this
License,
since
you
have
not
signed
it.
However,
nothing
else
grants
you
permission
to
modify
or
distribute
the
Program
or
its
derivative
works.
These
actions
are
prohibited
by
law
if
you
do
not
accept
this
License,
Therefore,
by
modifying
or
distributing
the
Program
(or
any
work
based
on
the
Program),
you
indicate
your
acceptance
of
this
License
to
do
so,
and
all
its
terms
and
conditions
for
copying,
distributing
or
modifying
the
Program
or
works
based
on
it.
6.
Each
time
you
redistribute
the
Program
(or
any
work
based
on
the
Program),
the
recipient
automatically
receives
a
license
from
the
original
licensor
to
copy,
distribute
or
modify
the
Program
subject
to
these
terms
and
conditions,
You
may
not
impose
any
further
restrictions
on
the
recipients'
exercise
of
the
rights
granted
herein,
You
are
not
responsible
for
enforcing
compliance
by
third
parties
to
this
License,
7.
If,
as
a
consequence
of
a
court
judgment
or
allegation
of
patent
infringement
or
for
any
other
reason
(not
limited
to
patent
issues),
conditions
are
imposed
on
you
(whether
by
court
order,
agreement
or
otherwise)
that
contradict
the
conditions of
this
License,
they
do
not
excuse
you
from
the
conditions of
this
License,
If
you
cannot distribute
so
as
to
satisfy
simultaneously
your
obligations
under
this
License
and
any
other
pertinent
obligations,
then
as
aconsequence
you
may
not
distribute
the
Program
at
all.
For
example,
ifapatent
license
would
not
permit
royalty-free redistribution of
the
Program
by
all
those
who
receive
copies directly
or
indirectly
through
you,
then
the
only
way
you
could
satisfy
both
it
and
this
License
would
be
to
refrain
entirely
from
distribution of
the
Program.
If
any
portion
of
this
section
is
held
invalid
or
unenforceable
under
any
particular circumstance,
the
balance
of
the
section
is
intended
to
apply
and
the
section
as
a
whole
is
intended
to
apply
in
other
circumstances.
It
is
not
the
purpose
of
this
section
to
induce
you
to
infringe
any
patents
or
other
property
right
claims
or
to
contest
validity
of
any
such
claims;
this
section
has
the
sole
purpose
of
protecting
the
integrity
of
the
free
software
distribution
system,
which
is
implemented
by
public
license
practices.
Many
people
have
made
generous
contributions
to
the
wide
range
of
software
distributed
through
that
system
in
reliance
on
consistent
application
of
that
system;
it
is
up
to
the
author/donor
to
decide'
if
he
or
she
is
willing
to
distribute
software
through
any
other
system
and
a
licensee
cannot
impose
that
choice.
This
section
is
intended
to
make
thoroughly clear
what
is
believed
to
be
a
consequence
of
the
rest
of
this
License,
8.If
the
distribution and/or
use
of
the
Program
is
restricted
in
certain
countries
either
by
patents
or
by
copyrighted
interfaces,
the
original
copyright holder
who
places
the
Program
under
this
License
may
add
an
explicit geographical
distribution
limitation
excluding
those
countries,
so
that
distribution
is
permitted
only
in
or
among
countries
not
thus
excluded,
In
such
case,
this
License
incorporates
the
limitation
as
if
written
in
the
body
of
this
License,
9.The
Free
Software
Foundation
may
publish
revised
and/
or
new
versions
of
the
General
Public
License
from
time
to
time,
Such
new
versions
will
be
similar
in
spirit
to
the
present
version,
but
may
differ
in
detail
to
address
new
problems
or
concerns,
