Importing Premake 4.3 as premake4 since premake 4 and premake 3 use incompatible \ 
scripts and they can be installed side by side. 
Premake4 is a build script generator. It generates build scripts for
gmake, xcode, visual studio and others. Premake4 uses Lua and it's input
files can use Lua scripting for build configuration tasks.
Premake 4 has been rewritten since Premake 3 and put under a different
license.
