Most GNU software, including some libraries, is covered by the ordinary GNU General Public License,
which was designed for utility programs. This license, the GNU Library General Public License, applies to
certain designated libraries. This license is quite different from the ordinary one; be sure to read it in
full, and don't assume that anything in it is the same as in the ordinary license.
The reason we have a separate public license for some libraries is that they blur the distinction we
usually make between modifying or adding to a program and simply using it. Linking a program with a
library, without changing the library, is in some sense simply using the library, and is analogous to
running a utility program or application program. However, in a textual and legal sense, the linked
executable is a combined work, a derivative of the original library, and the ordinary General Public
License treats it as such.
Because of this blurred distinction, using the ordinary General Public License for libraries did not
effectively promote software sharing, because most developers did not use the libraries. We concluded
that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the users of those programs of all
benefit from the free status of the libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while preserving your freedom as a user of
such programs to change the free libraries that are incorporated in them. (We have not seen how to
achieve this as regards changes in header files, but we have achieved it as regards changes in the actual
functions of the Library.) The hope is that this will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and modification 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, while the latter only works together with the library.
Note that it is possible for a library to be covered by the ordinary General Public License rather than by
this special one.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which contains a notice placed by the
copyright holder or other authorized party saying it may be distributed under the terms of this Library
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
