To "compile" the script NSIS (Nullsoft Scriptable Install System) is needed.

It can be found here: http://nsis.sourceforge.net/Main_Page

To add an additional language, make a new group of strings in the 
LanguageStrings.nsh file, and then insert '!insertmacro MUI_LANGUAGE "<Language_name>"' 
at roughly line 90 in Win32Script.nsi.

When packaging, make sure that architecture specific files are in the 
x64 and x86 folders. All other files (lua etc) should be as they
are when checked out, i.e. "../CorsixTH/*".
