Bug#851136: dh-make-perl: docs of where available modules -> debs found

[Kevin Ryde]

Package: dh-make-perl
Version: 0.92
Severity: wishlist
File: /usr/share/man/man1/dh-make-perl.1p.gz

It'd be good if the dh-make-perl man page summarised how it turns perl
module depends into deb package depends.  The details of this have
changed over time, but something short on what it looks for (and caches)
would be good.

I struck trouble recently with dh-make-perl reporting I only had an old
deb version available, despite new enough installed and in apt.  It took
a while for me to guess it was reading /var/lib/dpkg/available, which
for me was long out of date due to using apt not dselect I suppose.
That file could be listed in the "FILES" section.
