+"""
+Python part of radio playout (pypo)
+
+This function acts as a gateway between liquidsoap and the server API.
+Mainly used to tell the platform what pypo/liquidsoap does.
+
+Main case:
+ - whenever LS starts playing a new track, its on_metadata callback calls
+   a function in ls (notify(m)) which then calls the python script here
+   with the currently starting filename as parameter
+ - this python script takes this parameter, tries to extract the actual
+   media id from it, and then calls back to the API to tell about it about it.
