+# Bag of radio scripts
+
+This are some messy scripts. They don't work out of the box.
+You need maybe another tool like pallangana and maybe some
+python code to generate a radio html 
+[palanggana](https://git.vvvvvvaria.org/crunk/palanggana)
+
+It assumes you have icecast2, liquidsoap and python installed.
+
+This repo is meant to inspire other radio streamers that want to 
+tie together a few tools.
