    'Macro created 2007 by Lene Fredborg, DocTools - www.thedoctools.com
    'The macro creates a new document
    'and extracts insertions and deletions
    'marked as tracked changes from the active document

    '(e.g. formatting changes or inserted/deleted footnotes and endnotes)
    'Only insertions and deletions in the main body of the document will be extracted
    'The document will also include metadata
    'Inserted text will be applied black font color
    'Deleted text will be applied red font color
    
    'Minor adjustments are made to the styles used
    'You may need to change the style settings and table layout to fit your needs
