Here I work on the rulesets of Maperitive.
In this folder you can find the default rules that are included in Maperitive.
Here you can find rules I created on my own, rules sent to me and rules found somewhere on the net. Some rules are taken from the Maperitive rules category of the [OpenStreetMap Wiki}(http://wiki.openstreetmap.org/wiki/).
To use this rules you need to download them from here or clone this repository. Then you either drag&drop the ruleset on the Maperitive window or use the appropriate Maperitive commands.
