#
# Script to recursively search a directory and batch convert all files of a
# given file type into another file type via HandBrake conversion.
#
# To run in your environment set the variables:
#   hbcli - Path to your HandBrakeCLI
#   ffmpeg - Path to the ffmpeg
#
#   dirs - Array of starting directories for recursive search
#
#   input_file_type - Input file type to search for
#
#   output_file_type  - Output file type to convert into
#
#
# Change log:
# 2017-10-13: Publish to Gist.
# 2016-05-01: Added support for aditional processors.
# 2016-03-06: Initial release.  Tested on Mac OS X Lion.
# 2012-02-09: Added ability to process multiple directories.
# 2012-02-12: Added default system beep to signal end of all processing.
