71 @unnumbered Introduction
73 This manual contains detailed information about various features that
74 are too specialized to be included in the printed Emacs manual. It is
75 intended to be readable by anyone having a basic knowledge of Emacs.
76 However, certain sections may be intended for a more specialized
77 audience, such as Elisp authors. This should be clearly pointed out
78 at the beginning of these sections.
80 @c Note to authors - you need to be careful about cross-references to
81 @c topics in the Emacs manual. As a printed document, the xtra files
82 @c are separate from the Emacs manual; but as an info document, they
83 @c are part of the Emacs manual. Hence you need to use something like:
85 @c @ref{Comparing Files,,, emacs, the Emacs Manual},
88 @c @ref{Comparing Files},
91 Certain packages (or collections of related features) have their own
92 manuals, separate from the main Emacs manual. This manual is
93 intended as a complement, rather than an alternative, to reading those
94 additional manuals. In a nutshell, it is a collection of smaller
95 specialized features (or extra detail about standard features), too
96 small or too obscure to justify their own manual, or inclusion in the
97 printed Emacs manual. The chapters in this manual are, however,
98 included (at the relevant places) in the main Emacs manual when it is
99 formatted as an Info document.
101 Sections intended specifically for Elisp programmers can follow the
102 style of the Elisp manual. Other sections should follow the style of
