Pros:
Clean filesystem interface. Few new files. Easily extensible.

We're essentially adding a new mini-language to OWFS.

got? :) we don't need many files, just one :)
can be
echo 0 > ./LCD_COMMAND
we should set the index of each function like
0 = first_row
1 = second_rows
:) with this we can make everything with lcd :)
thankx ;)
