+FUNCTION
+	<<strcasecmp>>---case insensitive character string compare
+	
+INDEX
+	strcasecmp
+
+ANSI_SYNOPSIS
+	#include <string.h>
+	int strcasecmp(const char *<[a]>, const char *<[b]>);
+
+TRAD_SYNOPSIS
+	#include <string.h>
+	int strcasecmp(<[a]>, <[b]>)
+	char *<[a]>;
+	char *<[b]>;
+
+DESCRIPTION
+	<<strcasecmp>> compares the string at <[a]> to
+	the string at <[b]> in a case-insensitive manner.
+
+RETURNS 
+
+	If <<*<[a]>>> sorts lexicographically after <<*<[b]>>> (after
+	both are converted to upper case), <<strcasecmp>> returns a
+	number greater than zero.  If the two strings match,
+	<<strcasecmp>> returns zero.  If <<*<[a]>>> sorts
+	lexicographically before <<*<[b]>>>, <<strcasecmp>> returns a
+	number less than zero.
+
+PORTABILITY
+<<strcasecmp>> is in the Berkeley Software Distribution.
+
+<<strcasecmp>> requires no supporting OS subroutines. It uses
+tolower() from elsewhere in this library.
