How to write an extension for PHP4

I can't figure out how to create a new extension for php (version 4). I'm aware of apidoc.txt, and I found the script ext_skel in the ext directory, but I can't figure out how to include my new extension in the php build process. I'm running OpenBSD 2.5, with GNU m4 v1.4, autoconf v2.13, and automake v1.4, but I have no experience with these utilities; my previous projects have all used hand-built makefiles. Any help would be greatly appreciated, as I am currently stalled on my web project. Thanks, - Bruce __________________________________________________ Do You Yahoo!?
