** The order in which they are read are, pDefaults, $HOME/.Xdefaults,

**
** pDefaults is a string array of entries w/ each string representing one
** resource entry in the standard format used in the files. The array of

** Suffice it to say here that they are used to describe how to process the

** argc and argv are pointers for returning the unprocessed command line

** object for the propper handling of any command line parameters.
** After the creation of this object, any remaining command line processing
** should use the values returned by this constructor.
