For a moment there I thought you found how to work around that.  Oh,
well...

True.  However, these additions are trivial; patches welcome.

There's no way known to me to format all the manual pages in one go
except one by one, with GNU Find traversing the `man' tree and
converting every page.  A single man page can be formatted like so:

    groff -man -T ascii man/man1/tcpdump.1 > man\cat1\tcpdump.1

There can be complications with man pages that need preprocessing.
You can either find out what preprocessors are required by running the
`grog' shell script (supplied with Groff) and then using the command
it suggests, or you can pass all the preprocessor switches to Groff if
you don't care about slower conversion.

Btw, AFAIK, Unix `man' command doesn't save the reformatted page in
its catN directory either.  Some Unix systems have a separate program
called `catman' which formats all the unformatted pages for which
there's no corresponding formatted page.  I guess it should be easy to
write a `catman' clone using the code in man.c as the starting point.
