+Red was created out of the need to get work done, and the tool the author wanted to use, the language of REBOL, had a couple of drawbacks.
 It was not Open Sourced at that time and it is an interpreted language, what means that it is on average slow compared to a compiled language.
 
 Red, together with its C-level dialect Red/System, provides a language that covers the entire programming space you ever need to program something in.
-Red is a language heavily based on the language of REBOL. Where Red itself reproduces the flexibility of the REBOL language, the underlying language Red will be built upon, 
-Red/System, covers the more basic needs of programming like C can, being closer to the metal.

+Furthermore Red will be able to cross-compile Red source code without using any GCC like toolchain
 from any platform to any other platform. And it will do this all from a binary executable that is supposed to stay under 1 MB.
