   4 ## Script to convert the database of paraslash 0.2.x to version 0.3.x.
   5 ##
   6 ## Assumptions:
   7 ##      - para_server 0.2.x is running and the mysql selector is active
   8 ##      - para_server 0.3.x is running on another port
   9 ##      - The database of paraslash 0.3.x has been initialized (i.e.
  10 ##        para_client init has successfully been executed)
  11 ##      - All audio files in the mysql database of paraslash 0.2.x. have
  12 ##        already been added to the 0.3.x database (execute para_client add
  13 ##        /my/audio/file/dir to do that)
  14 ##
  15 ## The script converts the attribute table, the set attributes for each audio
  16 ## file, the image table and all image ids, and finally the lastplayed and the
  17 ## numplayed data.
  18 ##
  19 ## However, it  does not convert the paraslash stream definitions from 0.2.x to
  20 ## the moods of 0.3.x. You'll have to do this by hand.
