 `walint-mapserver` is a minimal implementation of a server that periodically
 fetches, lints, and adjusts maps from a set of git repositories, writing them
 to a path that can then be served by a webserver. It can be used as a (very

-`cwality-maps` is a small server for type-safe map templating, to be used if
