-Building ruby-opengl
-====================
-Pre-requisites
---------------
-General
---------------
-* C compiler (not needed for binary install on Windows)
-* ruby 1.8.5+ or ruby 1.9.0+
-* rake
-* mkrf 0.2.0+ (0.2.3+ for ruby 1.9)
-* rubygems 0.9.1+
-* OpenGL headers for OpenGL version 1.1 or later (not needed for binary install on Windows)
-* GLUT 3.7+ or API-compatible implementation (freeglut,OpenGLUT)
-Linux
---------------
-On Ubuntu or Debian systems, aside from Ruby you'll need ruby and
-some extra ruby related packages:
-* `ruby rdoc ri ruby1.8-dev`
-For OpenGL related headers you'll need the following packages:
-* `libgl1-mesa-dri libglu1-mesa freeglut3`
-* `libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev`
-On older Gentoo, Debian and Ubuntu, rubygems 0.9.0 will be installed by default
-in the packages.  This version of rubygems is INCOMPATIBLE with ruby-opengl.
-You'll need to install rubygems 0.9.1+ from source.
-On some distributions you may need 'xorg-dev' developer package.
-Mac OS X
---------------
-On OS X, you will need to install your own version of Ruby as the
-version that ships with OS X has known problems with properly building
-ruby-opengl bindings.  You'll also need XCode for gcc and tools.  Macports
-or fink should handle this cleanly.
-* To compile under Mac OS X you MUST install your own version of Ruby
-  as the version included with Tiger (1.8.2) has a broken rbconfig
-  and will fail to build the project properly.  Try either [MacPorts][],
-  [Fink][], or [building your own from source][].
-[Macports]: http://www.macports.org/
-[Fink]: http://finkproject.org/
-[building your own from source]: http://www.ruby-lang.org/en/downloads/
-Windows
---------------
-For manual build on Windows you need to have platform SDK and compiler that *must* match the one which was used for compiling ruby binary (for One-click ruby installer it is MSVC 6.0).
-You may also need 'glut.h' in SDK include directory, as the One-click ruby
-installer is missing it. You can copy the file from glut package at [glut homepage][].
-Alternatively, you can install the precompiled binary gem (see bellow).
-<b>Important note:</b> If you are using the One-click installer version 1.8.6-25 or earlier,
-you must delete or rename files 'opengl.so' and 'glut.so' in
-C:/ruby/lib/ruby/site_ruby/1.8/i386-msvcrt
-[glut homepage]: http://www.xmission.com/~nate/glut.html
-Build and installation
---------------
-Installing from rubygems
--------------------
-ruby-opengl should support being installed via gems now.  Just
-try 'gem install -y ruby-opengl' and it should pull down the gem
-and try to build the bindings for you automatically.
-For windows there is also pre-built binary windows gem available
-(i386-mswin32) which is compatible with the ruby one-click installer and does not need
-compiler or other mentioned tools installed.
-Manual Build instructions for all platforms (see above for platform-specific notes)
-------------------
-1. Make sure you have working ruby with rubygems installed
-	 and (if needed) appropriate developer packages (ruby-dev,ruby1.8-dev,...).
-2. Make sure you have working C compiler
-3. Install rake either from package or by running 'gem install rake'
-4. Install mkrf (0.2.0+) either from package or by running 'gem install mkrf'
-5. Make sure you have working OpenGL installation, this includes libGL,libGLU,
-   glut and (if needed) appropriate -dev or -devel packages.
-6. Run 'rake' at the top level of the project
-7. (OPTIONAL) Run 'rake test' to run unit tests to verify it works properly
-Installing manually built extensions
-------------------
-1. Run 'rake clean' to clean out the project
-2. Run 'rake gem' to create source gem from project
-3. Run 'gem install pkg/ruby-opengl-(version).gem' to compile and install the gem
-4. Done.
-Building binary gem (useful only for binary distribution of the project)
-------------------
-1. Run 'gem install gembuilder' to install the gembuilder package
-2. Run 'rake clean' to clean out the project
-3. Run 'rake gem' to build source gem
-4. Run 'gembuilder pkg/ruby-opengl-(version).gem' to compile the binary gem
-Testing
------------------
-To run unit tests:
-   $ rake test
-Note that the tests have the adverse effect of testing the underlying OpenGL
-implementation, so depending on your GL provider,drivers or OS, the tests may
-fail, crash, or not run at all, without affecting your ability to use the
-bindings.
-Running programs and examples
------------------
-To run a sample file, make sure the ruby-opengl gem is installed then:
-    $ cd examples
-    $ ruby -rubygems plane.rb
