+
+Find the first (leftmost) occurrence of a sequence of bytes within another
+sequence. This is the Perl version of C<strstr()>, extended to handle
+arbitrary sequences, potentially containing embedded C<NUL> characters (C<NUL>
+is what the initial C<n> in the function name stands for; some systems have an
+equivalent, C<memmem()>, but with a somewhat different API).
+
+Another way of thinking about this function is finding a needle in a haystack.
+C<big> points to the first byte in the haystack. C<big_end> points to one byte
+beyond the final byte in the haystack. C<little> points to the first byte in
+the needle. C<little_end> points to one byte beyond the final byte in the
+needle. All the parameters must be non-C<NULL>.
+
+The function returns C<NULL> if there is no occurrence of C<little> within
+C<big>. If C<little> is the empty string, C<big> is returned.
+
+Because this function operates at the byte level, and because of the inherent
+characteristics of UTF-8 (or UTF-EBCDIC), it will work properly if both the
+needle and the haystack are strings with the same UTF-8ness, but not if the
+UTF-8ness differs.
