[This is the fi r st r eleased ve r sion of the
Lesse r GPL. It also counts as the successo r
of the GNU Lib r a r y Public License, ve r sion
2, hence the ve r sion numbe r 2.1.]
Preamble
The licenses fo r most softwa r e a r e designed
to take away you r f r eedom to sha r e and
change it. By cont r ast, the GNU Gene r al
Public Licenses a r e intended to gua r antee
you r f r eedom to sha r e and change f r ee
softwa r e--to make su r e the softwa r e is f r ee
fo r all its use r s.
This license, the Lesse r Gene r al Public
License, a pp lies to some s p ecially
designated softwa r e p ackages--ty p ically
lib r a r ies--of the F r ee Softwa r e Foundation
and othe r autho r s who decide to use it. You
can use it too, but we suggest you fi r st think
ca r efully about whethe r this license o r the
o r dina r y Gene r al Public License is the
bette r st r ategy to use in any p a r ticula r case,
based on the ex p lanations below.
When we s p eak of f r ee softwa r e, we a r e
r efe rr ing to f r eedom of use, not pr ice. Ou r
Gene r al Public Licenses a r e designed to
make su r e that you have the f r eedom to
dist r ibute co p ies of f r ee softwa r e (and
cha r ge fo r this se r vice if you wish); that you
r eceive sou r ce code o r can get it if you want
it; that you can change the softwa r e and
use p ieces of it in new f r ee pr og r ams; and
that you a r e info r med that you can do these
things.
To
pr otect you r r ights, we need to make
r est r ictions that fo r bid dist r ibuto r s to deny
you these r ights o r to ask you to su rr ende r
these r ights. These r est r ictions t r anslate to
ce r tain r es p onsibilities fo r you if you
dist r ibute co p ies of the lib r a r y o r if you
modify it.
Fo
r exam p le, if you dist r ibute co p ies of the
lib r a r y, whethe r g r atis o r fo r a fee, you must
give the r eci p ients all the r ights that we
gave you. You must make su r e that they,
too, r eceive o r can get the sou r ce code. If
you link othe r code with the lib r a r y, you
must pr ovide com p lete object files to the
r eci p ients, so that they can r elink them with
the lib r a r y afte r making changes to the
lib r a r y and r ecom p iling it. And you must
show them these te r ms so they know thei r
r ights.
We pr otect you r r ights with a two-ste p
method: (1) we co p y r ight the lib r a r y, and (2)
we offe r you this license, which gives you
legal p e r mission to co p y, dist r ibute and/o r
modify the lib r a r y.
To pr otect each dist r ibuto r , we want to
make it ve r y clea r that the r e is no wa rr anty
fo r the f r ee lib r a r y. Also, if the lib r a r y is
modified by someone else and p assed on,
the r eci p ients should know that what they
have is not the o r iginal ve r sion, so that the
o r iginal autho r 's r e p utation will not be
affected by pr oblems that might be
int r oduced by othe r s.
Finally, softwa r e p atents p ose a constant
th r eat to the existence of any f r ee pr og r am.
We wish to make su r e that a com p any
cannot effectively r est r ict the use r s of a f r ee
pr og r am by obtaining a r est r ictive license
f r om a p atent holde r . The r efo r e, we insist
that any p atent license obtained fo r a
ve r sion of the lib r a r y must be consistent
with the full f r eedom of use s p ecified in this
license.
Most GNU softwa
r e, including some
lib r a r ies, is cove r ed by the o r dina r y GNU
Gene r al Public License. This license, the
GNU Lesse r Gene r al Public License,
a pp lies to ce r tain designated lib r a r ies, and
is quite diffe r ent f r om the o r dina r y Gene r al
Public License. We use this license fo r
ce r tain lib r a r ies in o r de r to p e r mit linking
those lib r a r ies into non-f r ee pr og r ams.
When a pr og r am is linked with a lib r a r y,
whethe r statically o r using a sha r ed lib r a r y,
the combination of the two is legally
s
p eaking a combined wo r k, a de r ivative of
the o r iginal lib r a r y. The o r dina r y Gene r al
Public License the r efo r e p e r mits such
linking only if the enti r e combination fits its
c r ite r ia of f r eedom. The Lesse r Gene r al
Public License p e r mits mo r e lax c r ite r ia fo r
linking othe r code with the lib r a r y.
We call this license the “Lesse r ” Gene r al
Public License because it does Less to
pr otect the use r 's f r eedom than the o r dina r y
Gene r al Public License. It also pr ovides
othe r f r ee softwa r e develo p e r s Less of an
advantage ove r com p eting non-f r ee
pr og r ams. These disadvantages a r e the
r eason we use the o r dina r y Gene r al Public
License fo r many lib r a r ies. Howeve r , the
Lesse r license pr ovides advantages in
ce r tain s p ecial ci r cumstances.
Fo r exam p le, on r a r e occasions, the r e may
be a s p ecial need to encou r age the widest
p ossible use of a ce r tain lib r a r y, so that it
becomes a de-facto standa r d. To achieve
this, non-f r ee pr og r ams must be allowed to
use the lib r a r y. A mo r e f r equent case is that
a f r ee lib r a r y does the same job as widely
used non-f r ee lib r a r ies. In this case, the r e is
little to gain by limiting the f r ee lib r a r y to
f r ee softwa r e only, so we use the Lesse r
Gene r al Public License.
In othe r cases, p e r mission to use a
p a r ticula r lib r a r y in non-f r ee pr og r ams
enables a g r eate r numbe r of p eo p le to use
a la r ge body of f r ee softwa r e. Fo r exam p le,
p e r mission to use the GNU C Lib r a r y in non-
f r ee pr og r ams enables many mo r e p eo p le
to use the whole GNU o p e r ating system, as
well as its va r iant, the GNU/Linux o p e r ating
system.
Although the Lesse
r Gene r al Public License
is Less pr otective of the use r s’ f r eedom, it
does ensu r e that the use r of a pr og r am that
is linked with the Lib r a r y has the f r eedom
and the whe r ewithal to r un that pr og r am
using a modified ve r sion of the Lib r a r y.
The pr ecise te r ms and conditions fo r
co p ying, dist r ibution and modification
follow. Pay close attention to the diffe r ence
between a “wo r k based on the lib r a r y” and a
“wo r k that uses the lib r a r y”. The fo r me r
contains code de r ived f r om the lib r a r y,
whe r eas the latte r must be combined with
the lib r a r y in o r de r to r un.
TERMS AND CONDITIONS FOR
COPYING, DISTRIBUTION AND
MODIFICATION
0. This License Ag r eement a pp lies to any
softwa r e lib r a r y o r othe r pr og r am which
contains a notice p laced by the
co p y r ight holde r o r othe r autho r ized
p a r ty saying it may be dist r ibuted unde r
the te r ms of this Lesse r Gene r al Public
License (also called “this License”).
Each licensee is add
r essed as “you”.
A “lib r a r y” means a collection of
softwa r e functions and/o r data
pr e p a r ed so as to be conveniently linked
with a pp lication pr og r ams (which use
some of those functions and data) to
fo
r m executables.
The “Lib r a r y”, below, r efe r s to any such
softwa r e lib r a r y o r wo r k which has been
dist r ibuted unde r these te r ms. A “wo r k
based on the Lib r a r y” means eithe r the
Lib r a r y o r any de r ivative wo r k unde r
co p y r ight law: that is to say, a wo r k
containing the Lib r a r y o r a p o r tion of it,
eithe r ve r batim o r with modifications
and/o r t r anslated st r aightfo r wa r dly into
anothe r language. (He r einafte r ,
t r anslation is included without
limitation in the te r m “modification”.)
“Sou r ce code” fo r a wo r k means the
pr efe rr ed fo r m of the wo r k fo r making
modifications to it. Fo r a lib r a r y,
com p lete sou r ce code means all the
sou r ce code fo r all modules it contains,
p lus any associated inte r face definition
files, p lus the sc r i p ts used to cont r ol
com p ilation and installation of the
lib r a r y.
Activities othe r than co p ying,
dist r ibution and modification a r e not
cove r ed by this License; they a r e outside
its sco p e. The act of r unning a pr og r am
using the Lib r a r y is not r est r icted, and
out p ut f r om such a pr og r am is cove r ed
only if its contents constitute a wo r k
based on the Lib r a r y (inde p endent of
the use of the Lib r a r y in a tool fo r w r iting
it). Whethe r that is t r ue de p ends on
what the Lib r a r y does and what the
pr og r am that uses the Lib r a r y does.
1. You may co p y and dist r ibute ve r batim
co p ies of the Lib r a r y's com p lete sou r ce
code as you r eceive it, in any medium,
pr ovided that you cons p icuously and
a ppr o pr iately p ublish on each co p y an
a ppr o pr iate co p y r ight notice and
disclaime r of wa rr anty; kee p intact all
the notices that r efe r to this License and
to the absence of any wa rr anty; and
dist r ibute a co p y of this License along
with the Lib r a r y.
You may cha r ge a fee fo r the p hysical
act of t r ansfe rr ing a co p y, and you may
at you r o p tion offe r wa rr anty pr otection
in exchange fo r a fee.
2. You may modify you r co p y o r co p ies of
the Lib r a r y o r any p o r tion of it, thus
fo r ming a wo r k based on the Lib r a r y,
and co p y and dist r ibute such
modifications o r wo r k unde r the te r ms
of Section 1 above, pr ovided that you
also meet all of these conditions:
a) The modified wo
r k must itself be a
softwa r e lib r a r y.
b)You must cause the files modified to
ca rr y pr ominent notices stating that
you changed the files and the date of
any change.
c) You must cause the whole of the wo r k
to be licensed at no cha r ge to all thi r d
p a r ties unde r the te r ms of this
License.
d)If a facility in the modified Lib r a r y
r efe r s to a function o r a table of data
to be su pp lied by an a pp lication
pr og r am that uses the facility, othe r
than as an a r gument p assed when
the facility is invoked, then you must
make a good faith effo
r t to ensu r e
that, in the event an a pp lication does
not su pp ly such function o r table, the
facility still o p e r ates, and p e r fo r ms
whateve r p a r t of its p u rp ose r emains
meaningful.
(Fo r exam p le, a function in a lib r a r y to
com p ute squa r e r oots has a p u rp ose
that is enti r ely well-defined inde p endent
of the a pp lication. The r efo r e,
Subsection 2d r equi r es that any
a pp lication-su pp lied function o r table
used by this function must be o p tional:
if the a pp lication does not su pp ly it, the
squa r e r oot function must still com p ute
squa r e r oots.)
These r equi r ements a pp ly to the
modified wo r k as a whole. If identifiable
sections of that wo r k a r e not de r ived
f r om the Lib r a r y, and can be r easonably
conside r ed inde p endent and se p a r ate
wo r ks in themselves, then this License,
and its te r ms, do not a pp ly to those
sections when you dist r ibute them as
se p a r ate wo r ks. But when you dist r ibute
the same sections as p a r t of a whole
which is a wo r k based on the Lib r a r y,
the dist r ibution of the whole must be on
the te r ms of this License, whose
p e r missions fo r othe r licensees extend
to the enti r e whole, and thus to each
and eve r y p a r t r ega r dless of who w r ote
it.
Thus, it is not the intent of this section to
claim
r ights o r contest you r r ights to
wo r k w r itten enti r ely by you; r athe r , the
intent is to exe r cise the r ight to cont r ol
the dist r ibution of de r ivative o r
collective wo r ks based on the Lib r a r y.
In addition, me r e agg r egation of
anothe r wo r k not based on the Lib r a r y
with the Lib r a r y (o r with a wo r k based on
the Lib r a r y) on a volume of a sto r age o r
dist r ibution medium does not b r ing the
othe r wo r k unde r the sco p e of this
License.
3. You may o p t to a pp ly the te r ms of the
o r dina r y GNU Gene r al Public License
instead of this License to a given co p y of
the Lib r a r y. To do this, you must alte r all
the notices that r efe r to this License, so
that they r efe r to the o r dina r y GNU
Gene r al Public License, ve r sion 2,
instead of to this License. (If a newe r
ve r sion than ve r sion 2 of the o r dina r y
GNU Gene r al Public License has
a pp ea r ed, then you can s p ecify that
ve r sion instead if you wish.) Do not
make any othe r change in these
notices.
Once this change is made in a given
co
p y, it is i rr eve r sible fo r that co p y, so
the o r dina r y GNU Gene r al Public
License a pp lies to all subsequent
co p ies and de r ivative wo r ks made f r om
that co p y.
This o p tion is useful when you wish to
co p y p a r t of the code of the Lib r a r y into
a pr og r am that is not a lib r a r y.
4. You may co p y and dist r ibute the Lib r a r y
(o r a p o r tion o r de r ivative of it, unde r
Section 2) in object code o r executable
fo r m unde r the te r ms of Sections 1 and
2 above pr ovided that you accom p any it
with the com p lete co rr es p onding
machine- r eadable sou r ce code, which
must be dist r ibuted unde r the te r ms of
Sections 1 and 2 above on a medium
customa
r ily used fo r softwa r e
inte r change.
If dist r ibution of object code is made by
offe r ing access to co p y f r om a
designated p lace, then offe r ing
equivalent access to co p y the sou r ce
code f r om the same p lace satisfies the
r equi r ement to dist r ibute the sou r ce
code, even though thi r d p a r ties a r e not
com p elled to co p y the sou r ce along
with the object code.
5. A pr og r am that contains no de r ivative of
any p o r tion of the Lib r a r y, but is
designed to wo r k with the Lib r a r y by
being com p iled o r linked with it, is
called a “wo r k that uses the Lib r a r y”.
Such a wo r k, in isolation, is not a
de r ivative wo r k of the Lib r a r y, and
the r efo r e falls outside the sco p e of this
License.
Howeve r , linking a “wo r k that uses the
Lib r a r y” with the Lib r a r y c r eates an
executable that is a de r ivative of the
Lib r a r y (because it contains p o r tions of
the Lib r a r y), r athe r than a “wo r k that
uses the lib r a r y”. The executable is
the r efo r e cove r ed by this License.
Section 6 states te r ms fo r dist r ibution of
such executables.
When a “wo
r k that uses the Lib r a r y”
uses mate r ial f r om a heade r file that is
p a r t of the Lib r a r y, the object code fo r
the wo r k may be a de r ivative wo r k of the
Lib r a r y even though the sou r ce code is
not. Whethe r this is t r ue is es p ecially
significant if the wo r k can be linked
without the Lib r a r y, o r if the wo r k is itself
a lib r a r y. The th r eshold fo r this to be t r ue
is not pr ecisely defined by law.
If such an object file uses only
nume
r ical p a r amete r s, data st r uctu r e
layouts and accesso r s, and small
mac r os and small inline functions (ten
lines o r less in length), then the use of
the object file is un r est r icted,
r ega r dless of whethe r it is legally a
de r ivative wo r k. (Executables
containing this object code p lus
p o r tions of the Lib r a r y will still fall unde r
Section 6.)
Othe
r wise, if the wo r k is a de r ivative of
the Lib r a r y, you may dist r ibute the
object code fo r the wo r k unde r the
te r ms of Section 6. Any executables
containing that wo r k also fall unde r
Section 6, whethe r o r not they a r e linked
di r ectly with the Lib r a r y itself.
6. As an exce p tion to the Sections above,
you may also combine o r link a “wo r k
that uses the Lib r a r y” with the Lib r a r y to
pr oduce a wo r k containing p o r tions of
the Lib r a r y, and dist r ibute that wo r k
unde r te r ms of you r choice, pr ovided
that the te r ms p e r mit modification of
the wo r k fo r the custome r ’s own use
and r eve r se enginee r ing fo r debugging
such modifications.
You must give
pr ominent notice with
each co p y of the wo r k that the Lib r a r y is
used in it and that the Lib r a r y and its
use a r e cove r ed by this License. You
must su pp ly a co p y of this License. If the
wo r k du r ing execution dis p lays
co p y r ight notices, you must include the
co p y r ight notice fo r the Lib r a r y among
them, as well as a r efe r ence di r ecting
the use r to the co p y of this License.
Also, you must do one of these things:
a) Accom
p any the wo r k with the
com p lete co rr es p onding machine-
r eadable sou r ce code fo r the Lib r a r y
including whateve r changes we r e
used in the wo r k (which must be
dist r ibuted unde r Sections 1 and 2
above); and, if the wo r k is an
executable linked with the Lib r a r y,
