# usage: ./eagle_package_release board_name [version]
#
# running this script will generate an electronics release file suitable for release on sourceforge and for production use.
# it will produce the following files in a .zip file:
# 
# * gerber
# * postscript
# * pdf
# * png
# * povray render
#
# installation / required tools:
