These commands should be typed "in-game", at the command line....
Using "The Quest For the Holy Snail" as a demo game here:
... to output a text based map of locations that you have already visited.
> drawmap all
.... to output a text based map of all locations (based on the navigation table).
Right now, this process isn't super smooth, so my apologies, but the text based maps need to opened in a text editor, then copy and pasted into https://www.planttext.com/ and the map will be rendered, courtesy of the plantuml and graphviz libraries.
The maps aren't north-centric, and therefore are sub-optimal for instant "grokking", but this will improve in future releases.
