<\body> documentation> As a general rule, you should avoid the use of sectioning commands inside the documentation and try to write small help pages on well identified topics. At a second stage, you should write recursive ``meta help files'' which indicate how to traverse the documentation in an automatic way. This allows the reuse of a help page for different purposes (a printed manual, a web-oriented tutorial, etc.). The style provides three markup macros for indicating how to traverse documentation. The macro is used to encapsulate regions with traversal information. It can be inserted using the entry in the or menu. The and macros indicate help pages which should be considered as a subsection and an appendix respectively, whereas the macro indicates a follow-up page. Each of these macros should be used inside a environment and each of these macros takes two arguments. The first argument describes the link and the second argument gives the physical relative address of the linked file. Typically, at the end of a meta help file you will find several or macros, inside one macro. At the top of the document, you should also specify a title for your document using the macro, as . When generating a printed manual from the documentation, a chapter-section-subsection structure will automatically be generated from this information and the document titles. Alternatively, one might automatically generate additional buttons for navigating inside the documentation using a browser. <\initial> <\collection>
