I had noticed it appears to be that way.  Lots of people doing their own
thing, often the same or very similar thing, who needs requirements for
example, with documentation that often leaves much to be desired.  I didn't
expect it to be easy to do, I do have some computer system background.

It would appear that Maperitive looks very promising and it can use a cached
.osm file saved from JOSM.  If any one wants to have a look at it the best
documentation appears to be here

That's not as easy as it sounds.
