policy-compliant interface from invoke-rc.d to local config files

 This package contains a script which is linked via the alternatives
 subsystem to /usr/sbin/policy-rc.d. This script looks for a local
 policy-rc.d script in /usr/local and /etc, providing a policy- and
 FHS-compliant way to interface invoke-rc.d with a local script.
 .
 Without this package, a local admin wanting to cleanly interface with
 invoke-rc.d is forced to drop a local binary to /usr/sbin and/or
 manually interface with the alternatives system. Both ways of doing
 this are clumsy and error-prone, so this package offers a clean way of
 interfacing with sysvrc and file-rc.
 .
 Since there are at least two packages containing their own version of
 invoke-rc.d, having a search path policy for policy-rc.d can be
 messy and is prone to be unstructured and uncoordinated.
 .
 Hence, having a dedicated package is the clean way of doing things.
 .
 This package has its upstream sources maintained in the Debian
 project, so there is no upstream URL.
