#  Crop all files in the script folder based on crop info loaded
#  from an external "info.txt" which contains info regarding
#  where to crop. Crop info format:
#  
#  6 01:30-02:28
#  10 03:30-05:29
#
# File should be name like this:
# 6 - Your file name.mp3
# 10 - Second file name.mp3
# 
# Usage: copy it to the folder with the .mp3 files and run it
# python crop.py
#
# It will create a folder "cropped" with the results.
# 
# Enjoy!

# NEEDS LAME, SOX and libsox-fmt-mp3!!!!
