<title>Introduction</>
<para>
This is a programers reference, so you will find lots of C code
and tecnical explanations all of it, as you can see, writen in
english, as I spect to share all this with the rest of the world
via The Internet so if you don't what to modify the code or find out
how the program works internaly, then the user manual will provably
benefit you most.

<chapter>
<title>SubSystems</title>
<para>
The program is divided into Subsystems, which communicate with
each other via a messaging facility.
</para>
<sect1><title>Procesor</title>
<para>
This is the subsystem responsable of executing the processes
and, usualy, is the one which generates all activity in the
other subsystems as their client.
</para>
&cpu-interface;
&cpu-config;
&CPU-simulation;
&process;
&cpu-status;
&process-queues;
&cpu-algorithms;
</sect1>
<sect1><title>I/O</title>
<para>
This subsystem is responsable of accepting block disk accesses,
simulating them and reporting its client when done.
</para>
&IO-interface;
&geometry;
&IO-simulation;
&io-request-queues;
&io-algorithms;
&IO;
<sect1><title>Memory</title>
<para>
This subsystem is responsable for accepting memory read and
write requests, managing memory for all processes: stealing
and swapping pages as necesary.
</para>
&mem-interface;
&mem-config;
&mem-algorithms;
&swap;
&mem-status;
&MEM;
</sect1>
<sect1><title>Clock</title>
<para>
This subsystem is responsable for generating a common time
reference for all other subsystems.
</para>
&CLOCK-interface;
</sect1>
<sect1><title>Requestor</title>
<para>
This subsystem is not important for the general understanding
of the program, but is included here for completnes. It is
there to allow the user to request I/O data and Memory manualy
acting as the client for those subsystems.
