+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.
