 **A client for HAFAS public transport APIs**. Sort of like [public-transport-enabler](https://github.com/schildbach/public-transport-enabler), but with a smaller scope. It also [contains customisations](p) for the following transport networks:

 ## Background
 
-There's [a company called HaCon](http://hacon.de) that sells [a public transport management system called HAFAS](https://de.wikipedia.org/wiki/HAFAS). It is [used by companies all over Europe](https://gist.github.com/derhuerst/2b7ed83bfa5f115125a5) to serve routing and departure information for apps. All those endpoints are similar, with the same terms and API routes, but have slightly different options, filters and enable features.

-`hafas-client` contains all logic for communicating with these, as well as serialising from and parsing to [*Friendly Public Transport Format (FPTF)* `1.0.1`](https://github.com/public-transport/friendly-public-transport-format/blob/1.0.1/spec/readme.md). Endpoint-specific customisations (called "profiles" here) increase the quality of the returned data.
