Licenses are intended to guarantee your freedom to share and change  
free software--to make sure the software is free for all its users.  
  
  This license, the Library General Public License, applies to some  
specially designated Free Software Foundation software, and to any  
other libraries whose authors decide to use it.  You can use it for  
your libraries, too.  
  
  When we speak of free software, we are referring to freedom, not  
price.  Our General Public Licenses are designed to make sure that you  
have the freedom to distribute copies of free software (and charge for  
this service if you wish), that you receive source code or can get it  
if you want it, that you can change the software or use pieces of it  
in new free programs; and that you know you can do these things.  
  
  To protect your rights, we need to make restrictions that forbid  
anyone to deny you these rights or to ask you to surrender the 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 source  
code.  If you link a program 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.  
  
  Our method of protecting your rights has two steps: (1) copyright  
the library, and (2) offer you this license which gives you legal  
permission to copy, distribute and/or modify the library.  
  
  Also, for each distributor's protection, we want to make certain  
that everyone understands that there is no warranty for this free  
library.  If the library is modified by someone else and passed on, we  
want its recipients to know that what they have is not the original  
version, so that any problems introduced by others will not reflect on  
the original authors' reputations.  
   
  Finally, any free program is threatened constantly by software  
patents.  We wish to avoid the danger that companies distributing free  
software will individually obtain patent licenses, thus in effect  
transforming the program into proprietary software.  To prevent this,  
we have made it clear that any patent must be licensed for everyone's  
free use or not licensed at all.  
  
  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
