+## Script to convert the database of paraslash 0.3.5 to version 0.4.x.
+##
+## Assumptions:
+## - para_server 0.3.5 is running
+## - "para_client check" reports no errors
+## - para_server 0.4.x is running, listens on another port and uses a
+## different afs database and a different afs socket
+## - The database of paraslash 0.4.x has been initialized (i.e.
+## para_client init has successfully been executed)
+## - All audio files in the 0.3.x database have already been added to
+## the 0.4.x database (execute para_client add /my/audio/file/dir to
+## do that)
+##
