Bug#123570: debian-policy: Add new virtual package foomatic-data

[Manfred Wassmann <debian-bugs@NCC-1701.B.Shuttle.de>]

Package: debian-policy
Version: N/A
Severity: wishlist

I'm currently packaging the foomatic printer/driver database and print
system.  The database is written in XML and is used to create specialized
printer description files that are needed by the included print filter
backends.

The PPD files are necessary for the foomatic system to work but it is not
strictly necessary to have the database installed which is rather large.  
The PPD files might well come with other packages and therefore I want to
use a virtual package foomatic-data that is provided by the foomatic-db
package as well as any other package containing PPD files for foomatic.

Please add foomatic-data to the virtual package list.
