Extracting HTML and Images from MHT and CHM?

smoon asks: "I've got a boatload of .CHM files, and have recently run across some .MHT files. The .MHT format appears to be how MS Internet Explorer saves a web site for offline viewing, and appears to be a basic MIME-format with all images inlined as base64 encoded data. I've poked around a bit looking for a utility that will extract the HTML files and associated graphics so that I can view these in Linux, but no luck so far. The .CHM format is billed as a 'compiled' HTML, and boils down to the equivalent of a tarball, in some Microsoft proprietary format, that shows a series of web pages. MS has a .CHM developers kit that allows you to extract all of the data, but the links stop working and it ends up not being very useful. Anyone know of a code that can extract the HTML and associated images from .CHM or .MHT files?"
