+# This is a simple script I wrote to convert my entire music library to mp3s for putting on my phone.
+# You need to have ffmpeg installed with support for all relevant formats for this to work.
+
+# HOW TO USE:
+# Place this script in the directory that your library's root directory is in, i.e. if your music
+# library is in ~/Music/Library, this script should be located at ~/Music/dirtomp3.sh
+# Set the variable "root" to the name of your library's root directory
+# Set "newroot" to the desired root directory of the output. This will be created if it doesn't exist.
+# The script should take care of the rest.
