Keep Right (keepright.at) is a Quality Assurance tool. It shows automatically detected errors on map or in list form. Keep Right is now available for whole of the planet, and can be used in many languages! Translation is done on a launchpad site: https://translations.launchpad.net/keepright

For a project of the week Steve created a little video (one of several Video tutorials)

Map Updates and modifications

Development

Sourceforge project with subversion repo

The README gives lots more details about installing and running Keep Right and writing your own checks.

Keep Right is developed by Harald Kleiner. He gave a talk about Keep Right internals at SOTM-EU 2011. Sources are licensed under GPLv2
