I have put up an interface for a little piece of code I use. It finds a
shortest path between 2 locations on batmud using predefined routes along
roads and portals and outputs a command you can copy&paste. This sevice is
only available in-mud, because 1) I don't have a web server and 2) it would
take too much effort to port this.

The syntax is "tell slobber path source destination". For example "tell
slobber path sc orion" ->

Slobber tells you '{edge_sc_lythp} {edge_lythp_ocp} {edge_ocp_orion} cost: 48'
Slobber tells you ';13 sw;3 w;transport ocp;20 e;11 e'

You can inquire the list of known locations with "tell slobber pathplaces".
Prepare for a minor spam. Some place names might be funny, don't ask where
each of them are, test.

Some of this info is available with "tell slobber pathinfo".

The paths avoid bridge trolls (you might take damage from not swimming) and
tries to avoid portals that cost money, but they use known free portals (yes,
also lythlandria's).

NOTE! You might end up running yourself to death on swamp, because of a bug or
some other reason (the paths have been tested though). I may have to ignore
you if you abuse this service. I may stop providing this service when I will
need exact timing like when I actually need to kill a monster (not in this
merchant reinc though).
