/**
* This sample demonstrates how the MergeDocx utility can
* be used to merge docx documents.
*
* The MergeDocx utility is a paid extension to docx4j.
* Purchases of this extension support the docx4j project.
* @see <a href="http://www.docx4java.org/blog/2010/11/merging-word-documents/">
* merging-word-documents blog post</a> for more info, or
* @see <a href="http://www.plutext.com/">www.plutext.com</a>
* or email sales@plutext.com if you want to buy it.
*
* To run the utility, you simply pass it a list of the
* docx you want to merge; it returns a new pkg containing
* the merged documents.
*
* This example looks a little more complex, since it
* has to use reflection, so that docx4j can still be
* built by users who don't have the MergeDocx code.
