Options available to cropit
 
-h, --help         shows options available to cropit .
 
-c, --crop         tells how much to crop the width of you avi file. The number
                   given is a percentage of the original, ex. -c 85 will crop
                   the width to 85% of the original. -c 100 will crop it to
                   100% of the original, which means no crop. The smaller the
                   number the larger the crop. The default crop is -c 81, or
                   81%. A typical range of 75 to 90 is prefered for most files.\n\n\n """
