Converts Open Flash Chart 2
chart description files (which are written in JSON format) into PNG images.

This tool is designed for automation. It can be run from a CRON job or
shell script---even in a headless environment (where a graphical display
is absent) as the "ofc2_to_png_headless.sh" shell script demonstrates.

To see help and usage information, run the `ruby ofc2_to_png.rb` command.
