you can do these things.
To protect your rights, we need to make restrictions that forbid dis-
tributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for you
if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
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 sour-
ce code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
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 the-
re 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 re-
putation will not be affected by problems that might be introduced
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 restricti-
ve 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 Gene-
ral Public License, applies to certain designated libraries, and is quite
different from the ordinary General Public License. We use this licen-
se 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-
