Everyone
is
permitted
to
copy
and
distribute
verbatim
copies
of
this
license
document,
but
changing
it
is
not
allowed.
Preamble
The
licenses
for
most
software
are
designed
to
take
away
your
freedom
to
share
and
change
it.
By
contrast,
the
GNU
General
Public
License
is
intended
to
guarantee
your
freedom
to
share
and
change
free
software
‐‐
to
make
sure
the
software
is
free
for
all
its
users.
This
General
Public
License
applies
to
most
of
the
Free
Software
Foundation’s
software
and
to
any
other
program
whose
authors
commit
to
using
it.
(Some
other
Free
Software
Foundation
software
is
covered
by
the
GNU
Lesser
General
Public
License
instead.)
You
can
apply
it
to
your
programs,
too.
When
we
speak
of
free
software,
we
are
referring
to
freedom,
not
price.
Our
General
Public
Licenses
are
designed
to
make
sure
that
you
have
the
freedom
to
distribute
copies
of
free
software
(and
charge
for
this
service
if
you
wish),
that
you
receive
source
code
or
can
get
it
if
you
want
it,
that
you
can
change
the
software
or
use
pieces
of
it
in
new
free
programs;
and
that
you
know
you
can
do
these
things.
To
protect
your
rights,
we
need
to
make
restrictions
that
forbid
anyone
to
deny
you
these
rights
or
to
ask
you
to
surrender
the
rights.
These
restrictions
translate
to
certain
responsibilities
for
you
if
you
distribute
copies
of
the
software,
or
if
you
modify
it.
For
example,
if
you
distribute
copies
of
such
a
program,
whether
gratis
or
for
a
fee,
you
must
give
the
recipients
all
the
rights
that
you
have.
You
must
make
sure
that
they,
too,
receive
or
can
get
the
source
code.
And
you
must
show
them
these
terms
so
they
know
their
rights.
We
protect
your
rights
with
two
steps:
(1)
copyright
the
software,
and
(2)
offer
you
this
license
which
gives
you
legal
permission
to
copy,
distribute
and/or
modify
the
software.
Also,
for
each
author’s
protection
and
ours,
we
want
to
make
certain
that
everyone
understands
that
there
is
no
warranty
for
this
free
software.
If
the
software
is
modified
by
someone
else
and
passed
on,
we
want
its
recipients
to
know
that
what
they
have
is
not
the
original,
so
that
any
problems
introduced
by
others
will
not
reflect
on
the
original
authors’
reputations.
Finally,
any
free
program
is
threatened
constantly
by
software
patents.
We
wish
to
avoid
the
danger
that
redistributors
of
a
free
program
will
individually
obtain
patent
licenses,
in
effect
making
the
program
proprietary.
To
prevent
this,
we
have
made
it
clear
that
any
patent
must
be
licensed
for
everyone’s
free
use
or
not
licensed
at
all.
The
precise
terms
and
conditions
for
copying,
distribution
and
modification
follow.
TERMS
AND
CONDITIONS
FOR
COPYING,
DISTRIBUTION
AND
MODIFICATION
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;
