Has anyone come across a Git or Hg plugin for "meaningful" diffs/merging/branching of OpenOffice or Microsoft word files.
I know I can 'checkin' .doc files but both Git and Hg treat them as binary blobs. I'd like to be able to do all (or at least many) of the normal revision based operations on the text of the file.
And yes, I do know that I should be using Latex or converting files back-and-forth between RTF. I'm just looking for a more "native" solution since I'm trying to manage collaboration between techies and "management people".
This is related to my question on Biostar here: http://biostar.stackexchange.com/questions/1749/writing-collaboration-with-source-control-and-microsoft-word
Thanks.
