Maps distribution

[quinet@montefiore.ulg.ac.be (Raphael Quinet)]

To all map creators out there: when you create a new set of
maps, please keep it all in a subdirectory, and distribute
a tar file with only these files in it.

This would be nice if there were several "plug-in" map
packages instead of a huge file with all maps in it.
When you get a new map, you would only have to change the
entry/exit point in the main map, then all new maps would
be available.

Well, I could be wrong, but I think this is a better
solution than the current one.  Any comments?
