-**Gravity** has been developed from scratch for the <a href="http://creolabs.com" target="_blank">Creo</a> project in order to offer an easy way to write portable code for the iOS and Android platforms. It is written in portable C code that can be compiled in any platform using a C99 compiler. VM code is about 2K lines long, multipass compiler code is about 3K lines and shared code is about 2K lines. Compiler and virtual machine together add less than 200KB to the executable size in a 64bit system.

 ## Special thanks
-A couple of open source projects helped Gravity in some areas. For closures implementation inspirations come from the elegant <a href="http://www.lua.org" target="_blank">Lua</a> programming language, specifically from the <a href="http://www.cs.tufts.edu/~nr/cs257/archive/roberto-ierusalimschy/closures-draft.pdf">Closures in Lua</a> document. For fibers, upvalues handling and some portions of the garbage collector my gratitude should go to <a href="http://journal.stuffwithstuff.com" target="_blank">Bob Nystrom</a> and his excellent <a href="https://github.com/munificent/wren">Wren</a> programming language. A very special thanks should also go to my friend **Andrea Donetti** who helped me debugging and testing various aspects of the language.
