Bug Description

if I do:

man volpack

I get:

man: ignoring unknown preprocessor `C'
man: ignoring unknown preprocessor `o'
man: ignoring unknown preprocessor `y'
man: ignoring unknown preprocessor `i'
man: ignoring unknown preprocessor `h'

 Manual page VolPack(3) line ?/? (END)

If I do:

zcat /usr/share/man/man3/VolPack.3.gz|nroff -man |more

it looks OK, so that's rather confusing as to where the problem lies.
Man for other pages looks OK.

This problem is caused by a missing preprocessor. It is solved with

sudo apt-get install grap

(grap — Kernighan and Bentley's language for typesetting graphs)

hmm ok; on precise with grap installed I still get those warnings when I man volpack, but it seems to render OK.

It's not very nice of it to have a man page which requires an extra preprocessor (I don't see anything in the manpage that looks special to need it?), and since it doesn't give any diagnostics to tell you it needs grap it's rather nasty for someone who just wants to read the page.

Fixed in 1.0b3-7, so at least in Disco.
