/**
 * \mainpage MIPS_SystemC
 * \section intro Introduction
 *
 * \c MIPS_SystemC is a MIPS simulator that uses SystemC to model a
 * MIPS pipelined architecture. The architecture is identical to 
 * the one presented
 * in "Computer Organization %and Design" by Hennessy&Patterson. 
 * \c MIPS_SystemC has a graphical user interface that allows %control of 
 * program execution
 * %and displays some of the signal values inside the architecture.
 *
 * \section compile Compiling
 *
 * To compile \c MIPS_SystemC you need SystemC 2.0.1
 * %and Qt version 2.x installed in your system.
 *
 * You must also define the environment variables \c QTDIR %and \c SYSTEMC. The 
 * correct value of these variables depend on the instalation of
 * Qt %and SystemC. As an example, \c QTDIR %and \c SYSTEMC may be initialised,
 * using the bash shell, by issuing the following commands:
 *
 *   <tt>export QTDIR=/usr/local/qt2</tt>
 *
 *   <tt>export SYSTEMC=/usr/local/systemc-2.0.1</tt>
 *
 * If those libraries are installed run \c make.
 *
 * \section run Running
 *
 *    To run \c MIPS_SystemC execute:
 *
 *    \c MIPS_SystemC
 *
 *    The initial contents of instruction memory %and data memory 
 *    can be changed by editing files \c instmem.hex %and \c datamem.dat, 
 *    respectively. These files are formatted as lists of hexadecimal
 *    numbers. (JLA:)
 *
