OTF conversion without OpenOffice

[brownh <brownh@historicalMaterialism.info>]

I received a .docx file appended in an e-mail, and need to extract and
convert it to a convenient format such as .html, .pdf, or plain .txt.

Apparently .docx can be viewed in Abiword and OpenOffice, but I do not
wish to install GUI applications, and so need a command-line format
conversion utility.

The best I find is OdfConverter
(odf-converter_1.0.0-2-getdeb1_i386.deb). I installed this, but it
lacks a manual and I have no idea how to use it. I gather that running
$ OdfConverter wihout argument will return a list of possible
arguments, but I don't seem to have any such OdfConverter executable.

Anyone know of a simple command-line convertion utility?
