>   CDocTemplate::Confidence CCamDocTemplate::MatchDocType(LPCTSTR lpszPathName, CDocument*& rpDocMatch)

    Author:     Rik_Heywood (Xara Group Ltd) <camelotdev@xara.com>
    Created:    9/5/95
    Purpose:    This function has been overiden from its MFC version. It is actually
                identical apart from the bit that checks to see if the document is already
                open. The MFC version of the function goes and looks at the files involved
                by calling AfxComparePaths(), but we just compare the paths. This stops the
                floppy drive from being accessed all the time if you have a document opened
                from a floppy drive (it also stops network problems if the conection to
                an open document goes away). I am not too sure what all the params mean.
