xtend is a daemon that is used in combination with a CM11a X10 interface (or compatible) that hooks to one of your serial ports. It executes arbitrary shell commands depending on what X10 commands it sees. It brings homeautomation at your fingertips.
Release Notes: Xtend's error handling has been improved. It tracks the state of X10 modules. It is compatible with Heyu versions prior to 1.28 (Heyu is a program to send x10 commands) The patch at http://heyu.tanj.com makes 1.2beta4 compatible with the newest Heyu (1.28 and higher).
Release Notes: Xtend now keeps track of the state of all X10 devices. This allows you to have conditional execution of commands (e.g. "do this only if lights A1 and P7 are on"). This data is also made available to all programs run by Xtend and to any interested process running on the computer. This new version is fully compatible with Heyu.
