This General Public License does not permit in- corporating your program into proprietary pro- grams. If your program is a subroutine library, you may consider it more useful to permit link- ing proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.

Preamble

This license, the Lesser General Public License, applies to some specially designated software
When we speak of free software, we are refer- ring to freedom of use, 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 soft- ware and use pieces of it in new free programs; and that you are informed that you can do these things.
To protect your rights, we need to make re- strictions that forbid distributors to deny you these rights or to ask you to surrender these 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 cop- ies 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, re- ceive or can get the source code. If you link other code with the library, you must provide
