-// ParseCommandLine
-//
-// Parse a command line (passed in args). If argc is non-NULL, it will
-// be set to the number of arguments. If argv is non-NULL, it will be
-// filled with pointers to each argument; argv[0] should be initialized
-// to point to a buffer large enough to hold all the arguments. The
-// return value is the necessary size of this buffer.
-//
-// Special processing:
-//   Inside quoted strings, \" becomes just "
-//                          \\ becomes just a single backslash          
-//							\c becomes just TEXTCOLOR_ESCAPE
-//   $<cvar> is replaced by the contents of <cvar>
