Title: Converting docx to text with unzip and sed

Periodically people email me Microsoft Word files which clearly contain
only text.  Fortunately, Word is now creating OOXML `.docx` files which
contain honest to goodness UTF-8 text (and lots of XML tags).  This is a
step up from the `.doc` format which as near as I could tell needed
special libraries to penetrate.

`.docx` files are zip archives.  The archived file `word/document.xml`
contains the text of the document itself and can be extracted with
`unzip file.docx word/document.xml`.

If you just want to see the text in a .docx file, you can strip out all
XML tags of `word/document.xml`, converting the P tag to a new
paragraph.  It's surprisingly legible for every .docx file I've seen so
far.  The sed command would be `s#</w:p>#\n\n#g;s#<[^>]*>##g`.

I made a shell script called `docx2txt` which contains the unzip command
to pipe to stdout, which is read by sed running that crazy script.  It
looks like this:

    #! /bin/sh

    unzip -qc "$1" word/document.xml | sed 's#</w:p>#\n\n#g;s#<[^>]*>##g'
