DXF stuff

Hi,
I am just getting started in this and decided I needed some software
tools first, before actually building a CNC controlled router. My end
project will be to carve letters or other 2-dimensional objects out of
wood.

My first software project is read-dxf.pl, which reads a file specified
on the command line and writes to the screen a list of all the lines
found.

Problem with that was, a large file would scroll off the page. So I
rewrote it in perl-tk to give the user an X window interface, with
scrollable windows and a file menu.

Are these two programs worthwhile, not sure, you tell me. I am working
on another program, which will move the xy cordinates into the postive
quadrant, if they are not there already.

In ways, these programs and some thoughts behind what I am doing are
at http://cnc.cjb.com

Need some feedback here, so let me know. Just signed up to the email
list today, even though I having been lurking for awhile.
