There is no package currently available. But it would be possible to make one and install it. But the 'groff' package and a few others would also be needed. Then there is, IIRC, some mechanism/script in OS2007 that automatically removes manpages installed with packages (but I could be wrong in this). In any case, most packages packed for OS2007 come without manpages. I strip the manpages away from the packages I maintain, for example.

Still, it would be perfectly possible to make a 'man' program package, if it's needed for a particular purpose - e.g. you already have a set of particular manpages you would want to use and install (in e.g. /usr/local/share/man) on the N800.

An alternative for a small, quick man system would be to require that manpages are pre-translated (this happens automatically when you read manpages on the desktop - the formatted page ends up in /var/cache/man/cat*/* on a desktop Debian system if set up that way -). Then the 'man' command would be a simple script. I used to have one laying around somewhere (years ago..)
