I noticed that the thbook wasn't clear on a small point so here is a little patch (against 0.3.10 - debian sources) to clarify:

Predefined map header contains some basic informations about cave: name, scale, north arrow, list of surveyors etc. It is fully customizable (see the chapter {\it Changing layout} for details). + <x> is easting (left-right on page). <y> is northing (up/down page). Ranges for |<x>| and |<y>| are -100--200. Lower-left corner of the map is |0 0|, upper-right corner is |100 100|. The header is aligned with the specified I will be providing a much more significant patch on the import command shortly (although some things still aren;t working quite right - so it may need some more discussion first).
