This document is intended for programmers. It describes the known technical differences between HOST and PHost. People who are writing client-side or host-side programs will get useful hints from this file for making their program PHost-aware and use PHost features optimally. Players usually do not need the information from this file.

This is a testing version.
It may be incomplete, and have more bugs (or features) than the public live version at planetscentral.com.
