wget like this:
wget --mirror --adjust-extension --convert-links --no-cookies http://tshepang.net -o log-main
I get a bunch of these messages:
Last-modified header missing -- time-stamps turned off.
I suppose that means that pages keep getting re-downloaded, even though I have them locally.
NOTE: I want this so that I don't have to re-download existing files each time I run the command mirror.
