*
* Description:
* This sample is a simple console application that might be used
* as a starting-point for an application that uses the Packaging API. This
* sample demonstrates the modification of an existing package, a word
* document.
*
* For the sake of simplicity, the sample does not update the last
* modified date, though this would be appropriate, nor does it modify history
* or other document parts and properties that may contain personally
* identifiable information. This sample is not sufficient to remove all
* authorship information from a document.
