This is an editor for the private resources file for AvnFPS.

The name of the resource is listed first. A short description in a
balloon popup window by pointing mouse cursor at the name. Value of
the resource is displayed on the right.  Depending on the resource
type it is:

Toggle button:	selected or not
Option menu:	allows selection from predefined values
Entry:		allows to type in values, such as width and height
Dialogs:
    File selection dialog:  to select audio file, resource *playFile
    Color chooser dialog:   to define colors
    Font chooser dialog:    to define fonts

When the editor starts, it tries to access configuration file
'awips/adapt/avnfps/etc/app-resources/X.n' where n is forecaster
number. If the file does not exist, a warning dialog is displayed and
the default file is read. If the default file does not exist,
hardcoded values are used.

Press 'Save' to write displayed values into your configuration file.
To restore default configuration, press 'Restore' for all resources,
or the 'Default' button to the left of each resource name to reset
them individually.
