+ * This is a regular expression library that implements a subset of Perl RE.
+ * Please refer to http://slre.sourceforge.net for detailed description.
+ *
+ * Usage example (parsing HTTP request):
+ *
+ * struct slre	slre;
+ * struct cap	captures[4 + 1];  // Number of braket pairs + 1
+ * ...
+ *
+ * slre_compile(&slre,"^(GET|POST) (\S+) HTTP/(\S+?)\r\n");
+ *
+ * if (slre_match(&slre, buf, len, captures)) {
+ *	printf("Request line length: %d\n", captures[0].len);
+ *	printf("Method: %.*s\n", captures[1].len, captures[1].ptr);
+ *	printf("URI: %.*s\n", captures[2].len, captures[2].ptr);
+ * }
+ *
+ * Supported syntax:
+ *	^		Match beginning of a buffer
+ *	$		Match end of a buffer
+ *	()		Grouping and substring capturing
+ *	[...]		Match any character from set
+ *	[^...]		Match any character but ones from set
+ *	\s		Match whitespace
+ *	\S		Match non-whitespace
+ *	\d		Match decimal digit
+ *	\r		Match carriage return
+ *	\n		Match newline
+ *	+		Match one or more times (greedy)
+ *	+?		Match one or more times (non-greedy)
+ *	*		Match zero or more times (greedy)
+ *	*?		Match zero or more times (non-greedy)
+ *	?		Match zero or once
+ *	\xDD		Match byte with hex value 0xDD
+ *	\meta		Match one of the meta character: ^$().[*+?\
