A shell script opens WinWord with the documents and a document template.
The document template contains a VBA macro that is run automatically.
It looks up the two documents and performs the comparison.
Unfortunately, the user's help is needed to construct the document template
with the macro from a plain text file, so we print the instructions from
the Makefile.
The README file contains instructions how to use this feature.

Ok, here's something that shows how git helps solve REAL PROBLEMS.
I've been using this for a day or two now with the MinGW port.
Other Windows prisoners might be interested, too.
Be sure to read the README and take a deap breath of the
fresh air.
;)
This was only tested with a localized version Microsoft Office 2000,
so your milage may vary.

+This directory contains facilities that allow to highlight changes
+between two revisions of WinWord documents.
+
+1. Installation:
+ a. Set the variable WINWORDEXE in ../../../config.mak to point
+ to your installed WinWord.exe
+ b. Run 'make'. This will fail with instructions to
+ create a document template. (It boils down to import
+ a macro file into the template.) Once you have completed
+ the instructions, 'make' will no longer fail.
+ c. Run 'make install'
+
+2. Activate diff in your repository
+ a. Define a custom diff driver:
+
+ $ git config diff.docdiff.command winworddiff
+
+ b. Use the custom driver for your Word documents, i.e. put
+ a line like this in your .git/info/attributes:
+
+ *.doc diff=docdiff
+
+3. Enjoy the diffs:
+
+ $ git diff HEAD~1.. -- UserManual.doc
+
+4. Caveats:
+
+ - Macros must be enabled.
+
+ - A new WinWord instance is started *for*each*document* that
+ is covered by the 'git diff' invocation; therefore, to be
+ on the safe side, always specify a path limiter. Use git-gui
+ and gitk to inspect diffs without path limiters.
