-Dname Defines name to processor, as if by #define. Default value is 1.
-Idir Searches named directory for files whose names do not begin with a backslash (/).
-o file Directs output to named file.
-s Operates silently; does not print input file names.
-t Formats listing for 80-column width.
-Uname Removes any initial definition of name.
