The problem with the TYP files is that the family and product IDs have
to match that of the map being generated.

I have the following workflow in place:

1. My "generic" TYP file is in a directory where the style directories also are.

2. My map building script copies the TYP file to the directory where
the current map is to be generated. In the copy process, the TYP file
is also renamed to a unique name matching the current map . (If I
recall, the TYP file name must also be unique if combining with
several different maps.)

3. A Perl script then adjusts the TYP file family and product IDs to
match that of the map being generated.

4. The adjusted TYP file is then passed as a parameter to mkgmap as
the map is generated.

Therefore, I would suggest that you think about distributing your TYP
file, potentially with the style files, but note that users will have
to adjust the name and IDs when they generate their own maps.

(And by the way, thanks for taking the initiative on this. Last year I
created a test public transportation layer, but have not had time to
document or distribute what I did.)

Cheers.
