Getting the script path of a commandline script

Anyone know how to get the script path (not the current working directory, but the actual path of the executing script) of a commandline script? I've dug through the docs and can't find this anywhere. None of the typical $_SERVER variables return the script path (although several of them return the filename, hooray for redundancy). The docs say several times that getcwd() will NOT return the path of the executing script, but they don't mention how to get it. Help. -- Ryan Grove ryan@wonko.com http://wonko.com/
