 \`build.sh' builds the WebGUI Runtime Environment.
  
  Usage: $0 [OPTIONS] [PACKAGES]

  Build switches cause only select applications to build.
  They can be combined to build only certain apps.
  
  Example: ./build.sh --perl            # only perl will be built
           ./build.sh --perl --apache   # only perl and apache will build
           ./build.sh --all             # build all (except wdk)
           ./build.sh --all --with-wdk  # build all including wdk 

  Options:

  --all             builds all packages
  --clean           cleans all pre-req folders for a new build
  --help            displays this screen
  --ia64            turns on special flags for building on 64-bit systems


  Packages:         (must be built in the order shown below)

  --utilities	    compiles and installs shared utilities
  --perl            compiles and installs perl
  --apache          compiles and installs apache
  --mysql	        compiles and installs mysql
  --imagemagick     compiles and installs image magick
  --perlmodules     installs perl modules from cpan
  --awstats         installs awstats
  --wre             installs WebGUI Runtime Environment scripts and API
