+/**
+ * str - string helper routines
+ *
+ * This is a grab bag of functions for string operations, designed to enhance
+ * the standard string.h.
+ *
+ * Note that if you define CCAN_STR_DEBUG, you will get extra compile
+ * checks on common misuses of the following functions (they will now
+ * be out-of-line, so there is a runtime penalty!).
+ *
+ *	strstr, strchr, strrchr:
+ *		Return const char * if first argument is const (gcc only).
+ *
+ *	isalnum, isalpha, isascii, isblank, iscntrl, isdigit, isgraph,
+ *	    islower, isprint, ispunct, isspace, isupper, isxdigit:
+ *		Static and runtime check that input is EOF or an *unsigned*
+ *		char, as per C standard (really!).
+ *
+ * Example:
+ *	#include <stdio.h>
+ *	#include <ccan/str/str.h>
+ *
+ *	int main(int argc, char *argv[])
+ *	{
+ *		if (argc > 1 && streq(argv[1], "--verbose"))
+ *			printf("verbose set\n");
+ *		if (argc > 1 && strstarts(argv[1], "--"))
+ *			printf("Some option set\n");
+ *		if (argc > 1 && strends(argv[1], "cow-powers"))
+ *			printf("Magic option set\n");
+ *		return 0;
+ *	}
