-= How to build ruby using Symbian SDK
-
-== Requirement
-
-(1) Nokia S60 SDK version 3.2 or later from http://www.forum.nokia.com/Resources_and_Information/Tools/Platforms/S60_Platform_SDKs/ with the latest OpenC plugin installed.
-
-    Note: if you want to build dynamic extensions support you need to install the latest version of GCC compiler from http://www.codesourcery.com/gnu_toolchains/arm/portal/release643. After that you need to apply a patch below to a header file (SDK_ROOT)\epoc32\include\gcce\gcce.h

-(2) If you want to build from SVN source, following command line binaries are required that are not a part of Symbain SDK.
-     * sed
-     * ruby 1.8
-     * svn
-
-== How to compile and install
-
-(1) Execute symbian\configure.bat on your build directory (symbian is default).
-
-(2) Run the following commands from symbian\group directory
-     'bldmake bldfiles'
-     'abld makefile gcce'
-     'abld build gcce urel ruby'
-     'abld freeze gcce ruby'
-     'abld build gcce urel'
-
-(3) Run 'makesis ruby.pkg' from symbian\sis directory
-     This command will create unsigned installation file ruby.sis. To sign it follow the guidlines from www.symbiansigned.com
-
-(4) In case dynamic extensions support was enabled repeat (3) for ruby_core_ext.pkg
-
-== Known problems
-
-Currently gems are not supported.
-Currently signals are supported with reduced functionality (see OpenC release notes.)
-Dynamic extensions could be installed only on internal drive "C".
