Template:R from template-generated category/doc

Usage
Place this template as the second unnamed parameter in Category redirect.


 * It is not necessary to append, because that is switched on by the presence of this template in the second unnamed parameter.


 * If R from category navigation is also applicable, as on Category:Years of the 19th century in Sri Lanka, do not use a pipe between the two "R from" templates. They should both be included in the second parameter.
