NavIt

The help text of maptool talks about a switch named “-o” or “--coverage” which is not implement at least since r2724 of maptool.c.

It seems to me as if this would be a:
• project suffering from bit-rot,
• project that has been superseded by another one or
• a feature not cleanly removed

It would be nice, if someone compent could clear this by eather implementing the command line switch or removing it from the help text.
