Maptitude - http://research.umbc.edu/~roswell/maptitude.html
Thanks Larry, for your notes! Here's a modification of my comparison
table, based on your remarks. (For mixlines I've changed "same map?" to
"No," and I've changed the file name to lower-case "mixlines.")
CopyLines mixlines
Two files must be in same directory? No Yes
Two files must be in same map? Yes No
Source must be DBD file? No Yes
Target must be DBD file? Yes Yes
Must have same file structure? Yes Yes
