  17 #  - Add more error checking

  20 #  - Not much error checking, esp. of arguments
  21 #  - Submitted via: line is created by template, when it really should be in send.

  70 A toolbox for doing cddb related stuff
  71
  72 Usage: $0 command [command_options]
  73
  74 Commands:
  75   parse file
  76         Get data out of a cddb file - dumps to stdout in a form
  77         source'able by the shell
  78
  79   send file address
  80         Mails a CDDB file to a specified address, using correct format.
  81         Category should be one of blues, classical, country, data, folk,
  82         jazz, newage, reggae, rock, soundtrack, or misc.
  83   template disc-id tracks
  84         Generates a template (empty) cddb file to stdout.  The command
  85         line should be essentially the output of cd-discid.
  86   query server proto user host disc-id tracks
  87         Looks up disc on server (should be of form "http://host/~cddb/cddb.cgi")
  88         remainder of command line is in the same form as that returned
  89         by the cd-discid program.
  90   read server proto user host disc-id genre
  91         CDDB file is dumped to stdout. File will contain an extra
  92         #CATEGORY= line, which leaves it a valid CDDB file but which will
  93         be recognized by parse and send commands. Uses wget, so if you
  94         need to use a proxy then just configure wget to do so. user and
  95         host will be used for identifying ourselves to the CDDB server.
  96   stat serverurl user host proto
  97         Check server status with given protocol. This can be used to check
  98         if the server supports given protocol. Most common values for proto
  99         should be 5 and 3. With 3 you will not get DYEAR and DGENRE fields
 100         in response.
