LaTeXML post-processing target for the DOC (MS Word), ODT (Open/LibreOffice Writer), and DocBook formats. Still very much under development, but eventually, you should be able to just type
latexmlc paper --destination=paper.docx
latexmlc paper --destination=paper.odt
latexmlc paper --format=DocBook --destination=paper.xml
to transform paper.tex into a document in one of the formats above.
== Development magic incantation: For ODT:
cd /path/to/KWARC-LaTeXML; git pull; perl Makefile.PL; make; sudo make install;
cd /path/to/LaTeXML-Plugin-Doc; git pull; perl Makefile.PL; make; sudo make install;
cd /path/to/testing/ODT/; latexmlc test.tex --destination=/tmp/test.odt --profile=odt
