shared library, the combination
of
the
two
is
legally
speaking a com-
bined work, a derivative
of
the original library.
The
ordinary General
Public License therefore permits such linking only
if
the entire com-
bination
fits
its criteria
of
freedom. The
Lesser
General Public License
permits more lax criteria for linking
other
code with the library.
We
call
this license the
"Lesser" General Public License because
it
does
Less
to
protect the user's freedom than the ordinary General Public
License.
It
also provides
other
free software developers
Less
of
an
advantage over competing non-free programs.
These
disadvantages
are the reason we use
the
ordinary General
Public
License for many
libraries. However, the
Lesser
license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need
to
en-
courage the widest possible
use
of
a certain library,
so
that
it
becomes
a
de-facto
standard.
To
achieve this, non-free programs
must
be
allowed
to
use
the library. A more frequent
case
is
that
a free library
does the same
job
as
widely used non-free libraries. In
this
case,
there
is
little
to
gain by limiting
the
free library
to
free software only,
so
we
use
the
Lesser
General Public
License.
In
other
cases,
permission
to
use a particular library in non-free pro-
grams enables a greater number
of
people
to
use
a large body
of
free
software. For example, permission
to
use the
GNU
C
Library in non-
free programs enables many more people
to
use
the whole
GNU
op
-
erating system,
as
well
as
its variant,
the
GNU/Linux operating system.
Although the
Lesser
General Public License
is
Less
protective
of
the
users
' freedom, it does ensure that
the
user
of
a program
that
is linked
with
the
Library
has
the freedom and
the
wherewithal
to
run
that
program using a modified version
of
the Library.
The precise terms and conditions for copying, distribution and mod-
ification follow.
Pay
close attention
to
the difference between a
"work
based on the
library"
and a
"work
that
uses
the library". The former
contains code derived from
the
library, whereas
the
latter
must be
combined
with
the library in order
to
run.

This
License Agreement applies
to
any software library or
other
program which contains a notice placed by the copyright holder
or
other
authorized
party
saying
it
may be
distributed
under
the
terms
of
this Lesser General Public License (also
called "this
License").
Each
licensee
is
addressed
as
"you':
A
"library
"
means a
collection
of
software
functions
and/or
data prepared
so
as
to
be conveniently linked
with
application
programs (which use some
of
those functions and data)
to
form
executables.
The "Library':
below, refers
to
any such software library
or
work
which has been
distributed
under these terms. A
"work
based
on the Library" means either the Library
or
any derivative work
under copyright law:
that
is
to
say
, a work containing the Library
or
a
portion
of
it, either verbatim
or
with
modifications
and/or
translated straightforwardly
into
another language. (Hereinafter,
translation
is
included
without
limitation in the term
"modifica-
tion':)
"Source code"
for a work means the preferred form
of
the work
for making modifications
to
it. For a library, complete source code
means
all
the source code for
all
modules
it
contains, plus any
as-
sociated interface definition files, plus the scripts used
to
control
compilation and installation
of
the library.
Activities
other
than copying, distribution and modification are
not
covered by this License; they
are
outside its scope.
The
act
of
running a program using the Library
is
not
restricted, and
output
from such a program
is
covered only
if
its contents constitute a
work based on the Library (independent
of
the
use
of
the Library
