Cisco Cisco IPICS Release 2.1 ライセンス情報

     License, applies to certain designated libraries, and is quite different

     from the ordinary General Public License. We use this license 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 combined

     work, a derivative of the original library. The ordinary General Public

     License therefore permits such linking only if the entire combination fits

     its criteria of freedom. The Lesser General Public License permits more

     lax criteria for linking other code with the library.

 

     We call this license the "Lesser" General Public License because it does

     Less to protect the user's freedom than the ordinary General Public

     License. It also provides other free software developers Less of an

     advantage over competing non-free programs. These disadvantages are the

     reason we use the ordinary General Public License for many libraries.

     However, the Lesser license provides advantages in certain special

     circumstances.

 

     For example, on rare occasions, there may be a special need to encourage

     the widest possible use of a certain library, so that it becomes a

     de-facto standard. To achieve this, non-free programs must be allowed to

     use the library. A more frequent case is that a free library does the same

     job as widely used non-free libraries. In this case, there is little to

     gain by limiting the free library to free software only, so we use the

     Lesser General Public License.

 

     In other cases, permission to use a particular library in non-free

     programs enables a greater number of people to use a large body of free

     software. For example, permission to use the GNU C Library in non-free

     programs enables many more people to use the whole GNU operating system,

     as well as its variant, the GNU/Linux operating system.

 

     Although the Lesser General Public License is Less protective of the

     users' freedom, it does ensure that the user of a program that is linked

     with the Library has the freedom and the wherewithal to run that program

     using a modified version of the Library.

 

     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, whereas the latter must be

     combined with the library in order to run.
