+ *
+ * Usage: timer ncomp nexec nsub
+ *	or
+ *	timer ncomp nexec nsub regexp string [ answer [ sub ] ]
+ *
+ * The second form is for timing repetitions of a single test case.
+ * The first form's test data is a compiled-in copy of the "tests" file.
+ * Ncomp, nexec, nsub are how many times to do each regcomp, regexec,
+ * and regsub.  The way to time an operation individually is to do something
+ * like "timer 1 50 1".
