'Basename' is the function that knows about the
syntax of pathnames and can select various portions
of the name based on its arguments.  It obtains input
pathnames from its argument list, or from standard input
if no arguments are specified, and prints the selected
components on standard output.  Options control the
portion of the file name selected as follows:
.sp
