; DCTl2u v0.1 (Dictionary Creation Tools) by erg0t
; -------------------------------------------------
;
; This program is one of many I have planed to do
; to facilitation of word dictionaries creation.
;
; With this program you can generate al Upercase
; and lowercase convinations of a word, starting
; from the lowercase word.
;
; Example:
; erg0t root # ./dic
; hola
; holA
; hoLa
; hOla
; Hola
; hoLA
; hOlA
; HolA
; hOLA
; HoLA
; HOLA
;
; NOTE: only works with lowercase alfabetic words!
; For any bug or suggesitions: ergot86@gmail.com
