What is this?

 This is the Global Premises Control package. It is intended to be a
complete solution to the DIY home automation. It provides you with a
daemon which will centralize all control functions, and some custom
programs for sound, remote control and things like that.
 The first steps to realizing the goal was made by Koen Martens. He wrote
the first daemon and made the first support programs. Other people got
interested and ported the GPC package to their homes. Since then it seemed
wise to coordinate development to prevent from having three different
versions of the package. It is currently under development and is far from


 15-03-98 - The first initiative
	    With the help of Henri Aanstoot and Marco Geels the first
	    cables were mounted in the ceiling at Waalstraat 136. This
            involved re-dedicating some high voltage lines for the low 
	    voltage used by GPC equipment.
	    The next few days Koen Martens spend his time writing software
	    to switch on the lights (which was not possible without
	    software anymore :). This software was very rudimentry and 
	    did not feauture the daemon yet.
 28-03-98   Version 1.0 was born.
	    The need for a global way to control the premises arose, and
	    Koen Martens decided to write a daemon which would control the
	    input and output lines, with support programs for the logic.
	    This resulted in global, the gpc daemon. 
	    Running on different servers there were programs to control
	    lights and lightswitches (light_control), sound (sound) and
	    the alarm clock (wakeup). 
 10-06-98   Version 2.0 (r0.2.0) was born. 
	    The support programs containing any logic had vanished,
	    instead the daemon had all the logic encoded in it.    
 03-07-98   Version 2.0 still.
	    - Added remote control receiver code.
 29-11-98   GPC r0.3.0
	    - Started coordinated development
 11-12-98   GPC r0.3.1
	    - Security support included, providing a (basic) interface
	      for protecting variables with passwords on a security level 
	      clearance basis.
	    - Global notify protocol added, clients can now register one
	      or more variables. This makes the old (0.3.0) polling method
	      obsolete thus reduces the network load dramatically.
	    - Logging library added.
 16-12-98   GPC pre-0.3.2
	    - Complete new configuration scheme! All the variable, port &
	      import configuration go into a set of config files. The
	      config directory is currently hardcoded to "/etc/gpc/".
	      Sample configuration files are included. 
	    - Warning! Inet.c is unstable. When you kill any client
	      connected to a gpc daemon, the daemon might crash if the
	      client had any vars registered.
	    - In progress: links from daemon to daemon. This is quit
              tricky, because the gpc_loop() function is not non-blocking
 17-12-98   GPC pre-
	    - Right, a super-unstable but very powerfull development 
	      release with:
	    - A web interface (cgi) by Venom!
	    - LIST command in the global commandmode 
 07-01-99   GPC 0.3.3
	    - Happy new year release
	    - No more 'Broken pipe's! Fixed the problem. This makes the
	      global daemon at least 1600% more stable.
	    - Improved web interface. Now you can evaluate and change 
	      variables from your favourite web browser. Graphical
	      interface on it's way.
	    - Fixed the gpc_list(..) function.


 The development is done on the following beta sites:

 - Subnet
	Location	: Waalstraat 136, Enschede, Netherlands
	Site coordinator: Koen Martens AKA gmc (
	Site description: Single floor appartment
			  3 occupants (1 human, 2 rats)
			  P60 32MB RAM running linux
			  486 8MB RAM running FreeBSD
			  486 8MB RAM running linux
			  DEC Writer
			  WYSE terminal
			  The 486 linux machine has the daemon, and is 
			  hooked up to the premises.
			  The P60 has a sound card and a RC receiver.
 - Lip-on-ice
	Location	: Lipperkerkstraat 321, Enschede, Netherlands
	Site coordinator: Willem-Jan Faber AKA aloha AKA xtz
	Site description: Three floor house
			  Four occupants (3 male, 1 female)
			  Connected to three other premises.
			  Computer list not yet in!
 - Venom
	Location	: P. Mondriaanstraat ??, Almelo, Netherlands
	Site coordinator: Sebastiaan Smit AKA venom (
	Site description: Three floor house

In progress

 The following projects are in progress right now:
	- A script language to describe the control logic for the daemon
		Koen Martens
	- An cgi interface for the http connectivity
	- Support for sharing variables on multiple daemons


 Use is for your own risk. We can not be held responsible for any damage
resulted from running any of this software.
 Keeping that in mind, usage is very simple but work needs to be done on
the documentation :)
