+## Script to convert the database of paraslash 0.2.x to version 0.3.x.
+##
+## Assumptions:
+##     - para_server 0.2.x is running and the mysql selector is active
+##     - para_server 0.3.x is running on another port
+##     - The database of paraslash 0.3.x has been initialized (i.e.
+##       para_client init has successfully been executed)
+##     - All audio files in the mysql database of paraslash 0.2.x. have
+##       already been added to the 0.3.x database (execute para_client add
+##       /my/audio/file/dir to do that)
+##
+## The script converts the attribute table, the set attributes for each audio
+## file, the image table and all image ids, and finally the lastplayed and the
+## numplayed data.
+##
+## However, it  does not convert the paraslash stream definitions from 0.2.x to
+## the moods of 0.3.x. You'll have to do this by hand.
