description             Lightweight Ruby

long_description        mruby is the lightweight implementation of the Ruby \
                        language complying to (part of) the ISO standard. \
                        Its syntax is Ruby 2.x compatible.  mruby can be \
                        linked and embedded within your application. We \
                        provide the interpreter program \"mruby\" and the \
                        interactive mruby shell \"mirb\" as examples. You can \
                        also compile Ruby programs into compiled byte code \
                        using the mruby compiler \"mrbc\". \"mrbc\" is also \
                        able to generate compiled byte code in a C source file.
