-Description: |-
-    μlogger ('micro-logger') is an application for continuous logging of location
-    coordinates, designed to record hiking, biking tracks and other outdoor
-    activities. Application works in background. Track points are saved at chosen
-    intervals and may be uploaded to dedicated server in real time. This client
-    works with <a href="https://github.com/bfabiszewski/ulogger-server">μlogger web server</a>.
-    Together they make a complete self owned and controlled client–server solution.
-
-    Features
-
-    * meant to be simple and small (μ);
-    * low memory and battery impact;
-    * uses GPS or network based location data;
-    * synchronizes location with web server in real time, in case of problems keeps retrying;
-    * alternatively works in offline mode; positions may be uploaded to the servers manually;
-    * configurable tracking settings
