  This program will automatically build and install a compiler and other
  tools used in the creation of homebrew software for the Sony Playstation 3
  videogame system.

 ==================
  How do I use it?
 ==================

 1) Set up your environment by installing the following software:

  autoconf, automake, bison, flex, gcc, libelf, make, makeinfo,
  ncurses, patch, python, subversion, wget, zlib, libtool, python,
  bzip2, gmp, pkg-config

  Specifically on debian-based systems, the following command line should
  be enough to install everything necessary:

  apt-get install autoconf automake bison flex gcc libelf-dev make \
    texinfo libncurses5-dev patch python subversion wget zlib1g-dev \
    libtool python-dev bzip2 libgmp3-dev pkg-config

 2) Add the following to your login script:

  export PS3DEV=/usr/local/ps3dev
  export PSL1GHT=$PS3DEV

  export PATH=$PATH:$PS3DEV/bin
  export PATH=$PATH:$PS3DEV/ppu/bin
  export PATH=$PATH:$PS3DEV/spu/bin

 3) Run the toolchain script:

  ./toolchain.sh
