Master Documents

[David Burleigh]

I'm trying to find a way to do on purpose what I once did by accident
(but I don't know how I did it). I have a master document containing
links to many subdocuments, and I would like to export the entire
contents to a normal ".odt" file in editable form. I tried File>Export
then choose File Type "ODF Text Document" but the resulting file still 
contains links to the subdocuments, not their editable contents.
