; puts.rbf - print some brainfuck code for a given string (print + clear)
;
; Dean Scarff's brain was last raped 27 July 2003.
;
; <Rich BrainFuck source file>
; To extract pure brainfuck source (and format it as well!):
; sed -e 's/;.*//' puts.rbf | tr -d '[:space:]' \
; | sed -e 's/\(.\{80\}\)/\1\n/g' > puts.bf
;
; Some usage examples:
; $ echo "My string" | bfi puts.bf > mystring.bf
;
; $ bfi puts # Then just type, hit Ctrl+D twice or ÿ when done
