:: NAME
::
::     compress - media compression script
::
:: SYNOPSIS
::
::     compress [SOURCE] [TARGET]
::
:: DESCRIPTION
::
::     This script uses ImageMagic and FFmpeg to batch compress image, audio and
::     video files.   The compression is achieved by proper configuration of the
::     encoding algorithms (up to x10) for images,  and by choice of codecs with
::     better compression ratio (up to x3) for audio and video files.
::
::     Use compress [SOURCE] [TARGET] to compress the desired media files, where
::     SOURCE is the wild card mask of the desired files (defaults to `*.*`) and
::     TARGET is the output directory (defaults to `%TEMP%`).
