Hi,
I've just used the man page to help me set up an (almost) working apt-ftparchive config file.
The manual was... outdated... in places, which I've tried to fix. I've done a whitespace cleanup of the docbook and picked up a few typos on the way through. I hope you'll be able to apply the patch(s) without problem, but I haven't tested them.
The attached file is a complete replacement for doc/apt-ftparchive.1.xml . I'll email the same file split into smaller, easier to review patches when I get a bug number.
Thanks,
kk
