Converting from HTML to ASCII requires an HTML parser. The libwww HTML
parser which is described in the quick guide:


As the libwww parser doesn't know about how to present things, it uses the
HText callout API so that the client can present it in the way it likes (in
the case of the libwww robot, we don't present it at all).

The line mode browser in fact tries to present the output in parsed form,
and so this is what you want to use. Try for example calling the line mode
browser (on Unix) like this

	www -n -na http://www.w3.org -o dump

It will give you an ASCII output of the W3C homepage save it in a file
called "dump". If you want it to go other places then this is easily fixed
in the www code.
