+This directory contains scripts not directly related to pypo
+These mainly are things related to liquidsoap & playout
+
+I added those scripts here to have them at hand for
+development and also to update/share them via svn
+
+
+scripts here:
+
+- ls_run.sh
+  wrapper to run liquid soap. makes sure that the "current" playlist is
+  filled with silence
+  
+- ls_script.liq (called by ls_run.sh)
+  the main liquidsoap control-script
+
+- ls_cue.liq (included by ls_script.liq)
+  contains a custom protocol that registers the cue-in/out values from the playlist script
+  
+- cue_file.py (called by ls_cue.liq)
+  a wrapper that does the actual cutting. 
+  it is called with: path_to_file[path] cue_in[ss.ms] cue_out[ss.ms] and does the mp3 cutting (with mp3cut)
+  returns a temporary file that can be used by ls (make sure to set "TEMP_DIR" in script)
