apa.cls is a LaTeX2e class file that makes your document conform to the APA Publication Manual (Fifth Edition, 2001) specifications for manuscripts or to the APA journal look found in journals like the Journal of Experimental Psychology etc. In addition, it provides a regular LaTeX-like output with a few enhancements and APA-motivated changes. This is a document *class* which uses (and modifies) some packages to achieve strictly defined formatting results and also uses the apacite package (sty & bst) for citations and references. If you only want APA-like citation for other kinds of documents (e.g., a thesis) use apacite.sty with an appropriate class. In order to use this document class you need some packages that may not be present in your LaTeX distribution. Please read apacls.txt carefully to understand what you need to install and what is possible with apa.cls, then read examples.txt carefully to understand how to use apa.cls (macros and instructions).
