========================
 Airtime Import Script
========================
There are two ways to import audio files into Airtime:

1) Use airtime-import to copy or move files into the storage folder.

   Copied or moved files will be placed into the folder:
   %s

   Files will be automatically organized into the structure
   "Artist/Album/TrackNumber-TrackName-Bitrate.file_extension".

2) Use airtime-import to add a folder to the Airtime library ("watch" a folder).

   All the files in the watched folder will be imported to Airtime and the
   folder will be monitored to automatically detect any changes. Hence any
   changes done in the folder(add, delete, edit a file) will trigger
   updates in Airtime library.
