Info: Code to use Figlet within Emacs

   From Mark Warren 415-506-4639 <mwa...@US.ORACLE.COM> off the Figlet 
list:


; This is a little ditty I put together to use figlet inside of emacs.
; I'm using version 2.0 and the -F and -p options (have these changed in
; 2.1?).
;
; Brief usage instructions: Save this message in the file figlet.el
; somewhere (preferrably somewhere on your emacs' load-path), then use
; "M-x load-file /somewhere/figlet.el" to load the elisp. Once that's
; done, mark a region then use the command "M-x figify-region" to figify
; that region.
;
; Cheers,
;
; Mark
;
; P.S. Maybe it'll windup in the util directory someday. :-)

;; Commentary:
;;      Run the figlet program on a region of text within emacs. This
;;      requires that you have the figlet package. Check archie for
;;      other sites, then check ftp.isu.edu.
