There getArgs and getProgName in System module. If you want parse this 
parameters there is System.Console.GetOpt. 

All the splitting, escaping and quotes interpretaion is done by shell. All 
what get program when starts is list of strings. Program name is actually 
arbitrary string. (At least on unices, it may work a bit differently on 
windows).
