+
+TRAD_SYNOPSIS
+	#include <string.h>
+	char *strpbrk(<[s1]>, <[s2]>)
+	char *<[s1]>;
+	char *<[s2]>;
+
+DESCRIPTION
+	This function locates the first occurence in the string
+	pointed to by <[s1]> of any character in string pointed to by
+	<[s2]> (excluding the terminating null character).
+
+RETURNS
