he library is released under the GPL with the following exception:
Linking this library statically or dynamically with other modules is
making a combined work based on this library. Thus, the terms and
conditions of the GNU General Public License cover the whole
combination.
As a special exception, the copyright holders of this library give you
permission to link this library with independent modules to produce an
executable, regardless of the license terms of these independent
modules, and to copy and distribute the resulting executable under
terms of your choice, provided that you also meet, for each linked
independent module, the terms and conditions of the license of that
module. An independent module is a module which is not derived from
or based on this library. If you modify this library, you may extend
this exception to your version of the library, but you are not
obligated to do so. If you do not wish to do so, delete this
exception statement from your version.

一直没弄明白是怎么回事,什么样才算是"derived from or based on"? 到底是允许不允许私有非GPL的项目使用?
今天在它的论坛上发现了这样的回答:

Yes, you can use the library in a closed source application. The
license comes with an exception to the GPL which explicitly allows this.
However,
you will need to link against the compiled assembly. Use and
modification of the source code require you to publish your code under
the same license.

原来只要不使用它的源代码,只是在编译和发布时链接它的dll,就可以对自己的代码选择自己的协议了--只要不违反你使用的任何其它组件的协议.
[Update]看来他们也觉得有必要解释一下了.现在SharpZipLib首页有了以下说明:
Bottom line In plain English this means you can use this library in commercial closed-source applications.
