47			`DESCRIPTION`
48			`<<towlower>> is a function which converts uppercase wide characters to`
49			`lowercase, leaving all other characters unchanged.`
50
51			`RETURNS`
52			`<<towlower>> returns the lowercase equivalent of <[c]> when it is a`
53			`uppercase wide character; otherwise, it returns the input character.`
54
55			`PORTABILITY`
56			`<<towlower>> is C99.`
