+One Line Statements
+-------------------
+
+To run a one line statement, append a 1 (one) to the arg list along with m and
+use like:
+
+c99sh -ms1 'printf("hi, there\n");'
+
+Note that single quotes around the statement makes echo command to use the
+string in it as is, which helps.

 PROGRAM, or if present in the current working directory when processing standard

 If compilation is successful, the exit status is that of PROGRAM.
