# Microstation DGN/CIT Files (www.bentley.com)
# Last updated July 29, 2005 by Lester Hightower
# DGN is the default file extension of Microstation/Intergraph CAD files.
# CIT is the proprietary raster format (similar to TIFF) used to attach
# raster underlays to Microstation DGN (vector) drawings.
