Re: [help-texinfo] Adding info documents to /usr/share/info

[Karl Berry]

    I've spent the last couple of hours unsuccessfully trying to hunt down
    the update-info-dir script that recreates the "dir" file from scratch.

I don't know about update-info-dir, but there is fix-info-dir and
gen-dir-node in the util/ subdir of the sources, and you can get them
from browsing the CVS repository at
http://savannah.gnu.org/projects/texinfo/ if you don't have the sources
already.  I've never run them myself and can't say for sure that they
are what you want.
