[pkg-s48-maint] Bug#473602: stop using cdbs System/Cpu fields

[Peter Eisentraut]

Package: scsh-0.6
Severity: normal

This package uses the cdbs control update feature.  As part of this feature 
one can specify the fields System: and Cpu: in place of Architecture: to 
allow a more fine-grained selection of architectures.  This feature was added 
with the apparent presumption that dpkg-dev would eventually understand this 
syntax as well, but in fact dpkg-dev now supports a different syntax.  
Therefore, the cdbs-specific syntax will be removed as soon as possible.

To switch to the dpkg-supported syntax, replace

Cpu: i386,arm,armel,...
System: any

by

Architecture: any-i386 any-arm any-armel ...

Also, add a build dependency on dpkg-dev (>= 1.13.12).
