Lintian tag information: usr-share-doc-symlink-to-foreign-package (type: error)

Description (from lintian-explain-tags)

If the package installs a symbolic link /usr/share/doc/*pkg1* -> *pkg2*,
then *pkg1* and *pkg2* must both come from the same source package.

The best solution is probably to stop symlinking the /usr/share/doc
directory for this package and instead include a real
/usr/share/doc/*pkg1* directory within *pkg1* with the appropriate
contents (such as the copyright and changelog.Debian.gz files).

Please refer to Copyright information (Section 12.5) in the Debian Policy
Manual for details.
