All reports of package-contains-devhelp-file-without-symlink for the archive. The extended description of this tag is:
This package contains a *.devhelp or *.devhelp2 file which is not in the devhelp search path (/usr/share/devhelp/books and /usr/share/gtk-doc/html) and is apparently not in a directory linked into the devhelp search path. This will prevent devhelp from finding the documentation.
If the devhelp documentation is installed in a path outside the devhelp search path (such as /usr/share/doc), create a symlink in /usr/share/gtk-doc/html pointing to the documentation directory.
This tag has not been emitted in any package tested by Lintian.
