The appendix package provides various ways of formatting the titles of appendices. Also (sub)appendices environments are provided that can be used, for example, for per chapter/section appendices. The word `Appendix' or similar can be prepended to the appendix number for article class documents. The word `Appendices' or similar can be added to the table of contents before the appendices are listed. The word `Appendices' or similar can be typeset as a \part-like heading (page) in the body. An appendices environment is provided which can be used instead of the \appendix command.
