new payment gateway extension

I'd like to contribute a new PHP extension for the TrustCommerce credit card payment gateway. Note that there is already at least one payment gateway extension included with PHP: the extension for Cybercash, which has gone out of business. I was wondering the proper procedure for submitting a new extension. I'd be happy to post a URL for a ready-to-include tarball, or maybe just commit it to CVS if given the required access. The stand-alone version of the PHP extension is already available on this page: http://trustcommerce.com/tclink.html So what's the best way to go about getting this included with PHP? -- Dan Helfman Software Engineer, TrustCommerce (626) 744-7700 x813 dan@trustcommerce.com http://www.trustcommerce.com
