 ## What's mruby
 
-mruby is the lightweight implementation of the Ruby language complying to (part of)
-the [ISO standard](http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=59579).

-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".  All those tools reside in the "bin" directory.  "mrbc" is also able to
-generate compiled byte code in a C source file, see the "mrbtest" program under the "test" directory
-for an example.

 ## Note for License
 
 mruby has chosen a MIT License due to its permissive license allowing
 developers to target various environments such as embedded systems.
 However, the license requires the display of the copyright notice and license
 information in manuals for instance. Doing so for big projects can be
-complicated or troublesome.
-This is why mruby has decided to display "mruby developers" as the copyright name
