You may be right.  I was about to reply that there could be a wiki-style
section in the mkgmap repository for user-contributed scripts, but then
again, I remember that Steve proposed (or opened?) several months ago
a "contrib" section of style files.  It was never mentioned again on this
list, so I suppose it can be too much trouble for most users to learn about
Subversion.

Right.

In any case, I would like to release some basic multi-layer map building
scripts in the mkgmap repository, as an example for mapmakers.  Sort of a
reference implementation with minimal or no TYP files, that is.  Examples
of "standard" map layer styles could include:

 * public ground transportation routes (bus, rail, ferry)
 * bicycle routes
 * traffic_calming, maxspeed, crossings, traffic signals, barriers, oneways
 * marine information (I don't know if this is applicable; Mark?)
 * flight routes

All these except the traffic layer could consist of lines only, with
very basic line styles.  The traffic layer could display custom symbols for
barrier=*, traffic_calming=*, highway=crossing and highway=traffic_signal.

Users with more specific needs can use their custom styles.  Examples
include the fancy line styles in the off-road maps of Extremecarver
and the colouring of roundabouts by road class as mentioned in
<http://www.cferrero.net/maps/maps_FAQ.html>.
