/**
* Set up the configuration file name at startup.
*
* <p>The Configuration File name variable holds the name used to load the configuration file
* during later startup processing. Applications invoke this method to handle the usual startup
* hierarchy:
*
* <UL>
* <LI>If an absolute filename was provided on the command line, use it
* <LI>If a filename was provided that's not absolute, consider it to be in the preferences
* directory
* <LI>If no filename provided, use a default name (that's application specific)
* </UL>
*
* This name will be used for reading and writing the preferences. It need not exist when the
* program first starts up. This name may be proceeded with <em>config=</em> and may not contain
* the equals sign (=).
*
* @param def Default value if no other is provided
* @param args Argument array from the main routine
