Cisco Cisco MediaSense Release 9.1(1) Licensing Information

 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        

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
