MODULE Configure:
================

Here you are informed of the environmental variables this  module needs. On
first startup. PAPCO read these from the defaults.config file in the modules
plot_read subdirectory; the paths set there will in general NOT be correct for
your installation. Use this widget to customize the module to your
configuration. Normally these environmental variables point at the data
directory containg the files needed by the module, or pointing at the URL
where they can be obtained. But ANY other use is possible, this is up to the
module author. Check the help on the main panel editor window for this module
for further details about this modules' environmental variables
