Subject: daemontools: add manpages from Debian
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using software, whose documentation is only available online is not
always convenient. This package has only online docuemntation and
upstream provides no manpages.

This commit extends the package by manpages prepared by Debian
developers. The manpages are added to a separate output. Listing of
the outputs of this package now looks like this:
