The first number is the name of the map tile. (Garmin map tiles are named
with numbers, and mkgmap uses 63240001 as the default name.)

The remaining numbers are the map coordinates.  The comment line shows
them in degrees (north of the equator and east of the Greenwich meridian).
If you divide the larger numbers by about 1/46604, you will get the degrees.

All lines starting with # appear to be ignored.

It seems so.

I have prepared a map of Finland at http://www.polkupyoraily.net/osm/
last week.  That is why I know. :-)
