Tool for converting SUDS .DRW files to something "modern".

[larsbrinkhoff]

Make a tool that reads a .DRW file and converts it to something that is easy to display on a modern computer. SVG, PHGL have been suggested.

Information about the file format can be found in Saildart, or from ITS archives:
