T
he 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 guaran-
t
ee
y
our freedom to share and chan
g
e free software--to make sure the software
i
s free for all its users. This General Public License applies to most of the Free Soft-
ware Foundation's software and to any other program whose authors commit to
usin
g
it.
(
Some other Free Software Foundation software is covered b
y
the GNU
Lesser General Public License instead.) You can apply it to your programs, too
.
When we s
p
eak of free software, we are referrin
g
to freedom, not
p
rice. Ou
r
G
eneral Public Licenses are desi
g
ned to make sure that
y
ou have the freedom to
d
istribute copies of free software (and charge for this service if you wish), that you
receive source code or can
g
et it if
y
ou want it, that
y
ou can chan
g
e the software
or use
p
ieces of it in new free
p
ro
g
rams; and that
y
ou know
y
ou can do these
thi
ngs
.
T

ate
t
o certain res
p
onsibilities for
y
ou if
y
ou distribute co
p
ies of the software, or if
y
ou
modif

.
F
or example, if you distribute copies of such a program, whether gratis or for a
fee,
y
ou must
g
ive the reci
p
ients all the ri
g
hts that
y
ou have. You must make sure
t

We

A
lso, for each author's
p
rotection and ours, we want to make certain that ever
y
-
one understands that there is no warranty for this free software. If the software is
modifi ed b
y
someone else and
p

avoid the dan
g
er that redistributors of a free

y
obtain

l
icenses, in effect making the program proprietary. To prevent this, we have made it
clear that an

Each licensee is addressed as "

.
A
ctivities other than copying, distribution and modifi cation 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)

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 ca-
t
ions 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
chan
g
ed the fi les and the date of an
y
chan
g
e
.
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 char
g
e to all third
p
arties 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 pr
i

sp
l
ay an announcement

,
and telling the user how to view a copy of this License. (Exception: if the Pro-
gram itself is interactive but does not normally print such an announcement, you
r
work based on the Program is not required to print an announcement.)
T
hese requirements apply to the modifi ed work as a whole. If identifi able sections
