Bug#587991: perl-policy: /etc/perl missing from Module Path

[Ansgar Burchardt <ansgar@2008.43-1.org>]

Package: debian-policy
Version: 3.9.0.0
Severity: minor

Hi,

perl/5.8.0-7 added /etc/perl to @INC:

  * Prepend /etc/perl to @INC to provide a standard location for
    configuration modules:

But this addition has never been documented in the Debian Perl Policy.
I suggest to add /etc/perl to the list of location in the "Module Path"
section.

A simple patch doing so is attached below, but it might be a good idea to
document what "configuration modules" are and what the "etc" tag means (only
"core", "vendor" and "site" are explained above, but none of those matches the
use of /etc/perl).

Regards,
Ansgar
