6: .Nd ordering of mandoc include files
7: .Sh DESCRIPTION
8: To support a cleaner coding style, the mandoc header files do not
9: contain any include directives and do not guard against multiple
10: inclusion.
11: The application developer has to make sure that the headers are
12: included in a proper order, and that no header is included more
13: than once.
14: .Pp
15: The headers and functions form three major groups:
16: .Sx Parser interface ,
17: .Sx Parser internals ,
18: and
19: .Sx Formatter interface .
20: .Pp
21: Various rules are given below prohibiting the inclusion of certain
22: combinations of headers into the same file.
23: The intention is to keep the following functional components
24: separate from each other:

1.2 schwarze 50: Note that mere usage of an opaque struct type does
1.1 schwarze 51: .Em not
52: require inclusion of the header where that type is defined.
53: .Ss Parser interface
54: Each of the following headers can be included without including
55: any other mandoc header.
56: These headers should be included before any other mandoc headers.
