Package: lintian
Version: 2.5.4
Severity: wishlist
The purpose of making a package "Multi-Arch: same" is to be to
co-installable with itself. However, this is only possible if all its
dependencies are either "Multi-Arch: same" or "Multi-Arch: foreign" (or
"Multi-Arch: allowed", but that's not supported yet.)
The attached prototype patch implements intra-source check for this. The
tag needs better name and better description. :)
