For example, if you distribute copies of the library, whether gra-
tis or for a fee, you must give the recipients all the rights that we
gave you. You must make sure that they, too, receive or can get the
source code. If you link other code with the library, you must pro-
vide complete object files to the recipients, so that they can relink
them with the library after making changes to the library and rec-
ompiling it. And you must show them these terms so they know
their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal per-
mission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there
is no warranty for the free library. Also, if the library is modified by
someone else and passed on, the recipients should know that what
they have is not the original version, so that the original author's
reputation will not be affected by problems that might be intro-
duced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot ef-
fectively restrict the users of a free program by obtaining a restric-
tive license from a patent holder. Therefore, we insist that any patent
license obtained for a version of the library must be consistent with
the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordi-
nary GNU General Public License. This license, the GNU Lesser Gen-
eral Public License, applies to certain designated libraries, and is
quite different from the ordinary General Public License. We use this
license for certain libraries in order to permit linking those libraries
into non-free programs.
When a program is linked with a library, whether statically or using a
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
