Lintian tag information: unused-debconf-template (type: information)

Description (from lintian-explain-tags)

Templates which are not used by the package should be removed from the
templates file.

This will reduce the size of the templates database and prevent
translators from unnecessarily translating the template's text.

In some cases, the template is used but Lintian is unable to determine
this. Common causes are:

- the maintainer scripts embed a variable in the template name in order to
allow a template to be selected from a range of similar templates (e.g.
db_input low start_$service_at_boot)

- the template is not used by the maintainer scripts but is used by a
program in the package

- the maintainer scripts are written in perl. Lintian currently only
understands the shell script debconf functions.

If any of the above apply, please install an override.
