NAME
     radio_rip - dumps every audio stream you can listen with your mplayer
     installation (yes, it\'s a possibility to record real streams) and encode 
     them to everything sox can manage. 
     Ogg Vorbis, mp3 ...  
 
SYNOPSIS
     radio_rip [ --help | RECORDING_TIME OUTPUT_FILE STREAM_URL ] 
 
DESCRIPTION
     radio_rip connect via mplayer to a audio stream send the raw output
     to a named pipe. Sox reads from the named pipe and transform to a format
     you refer in OUTPUT_FILE by the last 3 characters. 
     If there is no free streaming port available radio_rip retry that often you 
     define in the config section of the radio_rip script. The default is 200. 
     It\'s a god idea to use radio_rip in combination with cron or at and sometimes
     http://gpl.coulmann.de/day_of_month.html is very helpful. 
     Of corse, you need a mplayer and a sox installation.
 
     RECORDING_TIME 
         is the duration of the recording in minutes 
     OUTPUT_FILE 
         is the location of the output codec. The last 3 characters define the format
       e.g. ~/favorite_radio_show.ogg will generate a ogg vorbis file
         please refer to sox (1)           
     STREAM_URL 
         is the url of any audio stream your mplayer installation can handle
         please refer to mplayer (1)
