Cisco Cisco IPICS Release 2.1 Licensing Information

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 limitation in the term

"modification".)

 

"Source code" for a work means the preferred form of the work for making modifications to it. For a library,

complete source code means all the source code for all modules it contains, plus any associated interface definition

files, plus the scripts used to control compilation and installation of the library.

 

Activities other than copying, distribution and modification are not covered by this License; they are outside its

scope. The act of running a program using the Library is not restricted, and output from such a program is covered

only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing

it). Whether that is true depends on what the Library does and what the program that uses the Library does.

 

1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any

medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice

and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty;

and distribute a copy of this License along with the Library.
