====================
  What does this do?
 ====================

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

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

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

      autoconf, automake, bison, bzip2, cmake, flex, g++, gcc, git,
      gmp, libtool, make, makedepend, makeinfo, ncurses,
      patch, pkg-config, python, subversion, wget, yaml, ziplib, zlib

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

      apt-get install autoconf automake bison build-essential bzip2 \
        cmake flex git libgmp3-dev libncurses5-dev \
        libtool libzip-dev pkg-config python python-dev subversion \
        texinfo wget libyaml-dev zlib1g-dev xutils-dev 

  2) Add the following to your login script:

    ## Set up the environment.
    export VITASDK=/usr/local/vitasdk

    ## Set up the path.
    export PATH=$PATH:$VITASDK/bin

  3) Run the toolchain script:

    ./toolchain.sh

  4) Enjoy!
