All reports of cannot-check-whether-usr-share-doc-symlink-points-to-foreign-package for the archive. The extended description of this tag is:

There is a symlink /usr/share/doc/pkg1 -> pkg2 in your package. This means that pkg1 and pkg2 must both come from the same source package. I can't check this right now however since I'm only checking a binary package and I only can check this when I'm checking both the binary and the corresponding source package.

Severity: minor, Certainty: possible

Check: copyright-file, Type: binary
