+FUNCTION
+	<<strcasestr>>---case-insensitive character string search
+	
+INDEX
+	strcasestr
+
+ANSI_SYNOPSIS
+	#include <string.h>
+	char *strcasestr(const char *<[s]>, const char *<[find]>);
+
+TRAD_SYNOPSIS
+	#include <string.h>
+	int strcasecmp(<[s]>, <[find]>)
+	char *<[s]>;
+	char *<[find]>;
+
+DESCRIPTION
+	<<strcasestr>> searchs the string <[s]> for
+	the first occurrence of the sequence <[find]>.  <<strcasestr>>
+	is identical to <<strstr>> except the search is
+	case-insensitive.
+
+RETURNS 
+
+	A pointer to the first case-insensitive occurrence of the sequence 
+	<[find]> or <<NULL>> if no match was found.
+
+PORTABILITY
+<<strcasestr>> is in the Berkeley Software Distribution.
+
+<<strcasestr>> requires no supporting OS subroutines. It uses
+tolower() from elsewhere in this library.
