Double Duty Class

This class actually performs two distinct functions. It will register itself as a post-process observer. It will also register itself as a contributed tool. This section will discuss only the event observer portion of the class.

Do the Work

The update() method has been modified to perform specific actions for the post process of the build process for specific minor IDs.

BuildType_DataFile
This observer will check the file to verify that it is a ProvideX keyed file and will then convert it to XML.
BuildType_OtherFile
This observer will verify that the file has an .xml extension and will then attempt to convert (or create) a ProvideX data file. The conversion logic requires that the XML file be defined for the schema 'providex'. 
update:
enter aPvxState 

	/*
	 * This observer is triggered when an incremental build is initiated on a
	 * data file.
	 *
	 * If the source file ends with the XML extension, it will be converted to
	 * a PVX keyed file.  Otherwise, the file header is read to verify that this
	 * is in fact a PVX keyed file and then it is converted to XML.
