pear code and licenses/disclaimers

Hi, I have some code I've been working on that I'd like to submit to Pear. I have a question about licenses. If I submit code to Pear, how does the licenses and disclaimers work? Can we have our own license, or must we assume the PHP license? Code that I've released in the past had our company's copyright notice and was under the GNU license. I'd like to know what should be done with Pear code. Thanks Monte
