[mkgmap-dev] Commit: r2658: Use mkgmap:street tag to get street name for house number search

Fri Jul 19 16:30:48 BST 2013

oh, found out that:
name=* {set mkgmap:street='${name}'}

doesn't have any performance impact. Dunno why this is so much 
quicker.... but it works. So it's good and documented here for everyone 
wondering how to use mkgmap:street.
