      process-av-files

      Enables the vetting of audio and video files. 

      For each file, plays it with mplayer, and prompts for what you would like to do 
      with that file, moving the file to one of the following subdirectories:

      * deletes
      * saves
      * undecideds

      This software uses mplayer to play audio files. Use cursor keys to move forwards/backwards in time.
      Press 'q' or 'ESC' to abort playback and specify disposition of that file.

      Run `man mplayer` for more on mplayer.

      Assumes all files in the current directory are files playable by mplayer.
      Creates subdirectories in the current directory: deletes, saves, undecideds.
      Logs to hidden directory '.process-av-files.log'
