And easier to navigate when they have been converted to html, e.g.
http://manpages.courier-mta.org/mansection1.html
You should keep in mind that these are likely not current or in sync'
with your system.
http://manpages.debian.net/ is pretty much in sync i guess.
the only "problem with that site is that it cgi generates the pages, so its not indexed by google, one of the reasons that they did it differently for the ubuntu version.
in my turn i made the http://manpages.songshu.org basically copying ubuntu's site and applied it to debian, nothing special further but it was a nice practice material.
