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