Tips and Hints
**************
   Here are some tips for writing Texinfo documentation:
   * Write in the present tense, not in the past or the future.
   * Write actively!  For example, write "We recommend that ..." rather
     than "It is recommended that ...".
   * Use 70 or 72 as your fill column.  Longer lines are hard to read.
   * Include a copyright notice and copying permissions.
Index, index, index!
....................
   Write many index entries, in different ways. Readers like indices;
they are helpful and convenient.
   Although it is easiest to write index entries as you write the body
of the text, some people prefer to write entries afterwards.  In either
case, write an entry before the paragraph to which it applies.  This
way, an index entry points to the first page of a paragraph that is
split across pages.
   Here are more hints we have found valuable:
   * Write each index entry differently, so each entry refers to a
     different place in the document.  The index of an Info file lists
     only one location for each entry.
   * Write index entries only where a topic is discussed significantly.
      For example, it is not useful to index "debugging information" in
     a chapter on reporting bugs.  Someone who wants to know about
     debugging information will certainly not find it in that chapter.
   * Consistently capitalize the first word of every index entry, or
     else use lower case.  According to convention, you should
     capitalize the first word of an index entry.  However, this
     practice may make an index look crowded.  Some writers prefer
     lower case.  Regardless of which you prefer, choose one style and
     stick to it.  Mixing the two styles looks bad.
   * Always capitalize or use upper case for those words in an index for
     which this is proper, such as names of countries or acronyms.
   * Write the indexing commands that refer to a whole section
     immediately after the section command, and write the indexing
     commands that refer to the paragraph before the paragraph.
     For example:
          @section The Dog and the Fox
          @cindex Jumping, in general
          @cindex Leaping

          @cindex Dog, lazy, jumped over
          @cindex Lazy dog jumped over
          @cindex Fox, jumps over dog
          @cindex Quick fox jumps over dog
          The quick brown fox jumps over the lazy dog.
     (Note that the example shows entries for the same concept that are
     written in different ways--`Lazy dog', and `Dog, lazy'--so readers
     can look up the concept in different ways.)
Blank lines
...........
   * Insert a blank line between a sectioning command and the first
     following sentence or paragraph, or between the indexing commands
     associated with the sectioning command and the first following
     sentence or paragraph, as shown in the tip on indexing.
     Otherwise, a formatter may fold title and paragraph together.
   * Always insert a blank line before an `@table' command and after an
     `@end table' command; but never insert a blank line after an
     `@table' command or before an `@end table' command.
     For example:
          Types of fox:

          @table @samp
          @item Quick
          Jump over lazy dogs.

          @item Brown
          Also jump over lazy dogs.
          @end table

          @noindent
          On the other hand, ...
     Insert blank lines before and after `@itemize' ... `@end itemize'
     and `@enumerate' ... `@end enumerate' in the same way.
Complete phrases
................
   Complete phrases are easier to read than ....
   * Write entries in an itemized list as complete sentences; or at
     least, as complete phrases.  Incomplete expressions ... awkward
     ... like this.
   * Write the prefatory sentence or phrase for a multi-item list or
     table as a complete expression.  Do not write "You can set:";
     instead, write "You can set these variables:".  The former
     expression sounds cut off.
Editions, dates and versions
............................
   Write the edition and version numbers and date in three places in
every manual:
  1. In the first `@ifinfo' section, for people reading the Texinfo
     file.
  2. In the `@titlepage' section, for people reading the printed manual.
  3. In the `Top' node, for people reading the Info file.
Also, it helps to write a note before the first ifinfo section to
explain what you are doing.
For example:
     @c ===> NOTE! <==
     @c Specify the edition and version numbers and date
     @c in *three* places:
     @c   1. First ifinfo section  2. title page  3. top node
     @c To find the locations, search for !!set

     @ifinfo
     @c !!set edition, date, version
     This is Edition 4.03, January 1992,
     of the @cite{GDB Manual} for GDB Version 4.3.
     ...
Definition Commands
...................
   Definition commands are `@deffn', `@defun', `@defmac', and the like,
and enable you to write descriptions in a uniform format.
   * Write just one definition command for each entity you define with a
     definition command.  The automatic indexing feature creates an
     index entry that leads the reader to the definition.
   * Use `@table' ... `@end table' in an appendix that contains a
     summary of functions, not `@deffn' or other definition commands.
Capitalization
..............
   * Capitalize `Texinfo'; it is a name.  Do not write the `x' or `i'
     in upper case.
   * Capitalize `Info'; it is a name.
   * Write TeX using the `@TeX{}' command.  Note the uppercase `T' and
     `X'.  This command causes the formatters to typeset the name
     according to the wishes of Donald Knuth, who wrote TeX.
Spaces
......
   Do not use spaces to format a Texinfo file, except inside of
`@example' ... `@end example' and similar commands.
   For example, TeX fills the following:
         @kbd{C-x v}
         @kbd{M-x vc-next-action}
            Perform the next logical operation
            on the version-controlled file
            corresponding to the current buffer.
so it looks like this:
     `C-x v' `M-x vc-next-action' Perform the next logical operation on
     the version-controlled file corresponding to the current buffer.
In this case, the text should be formatted with `@table', `@item', and
`@itemx', to create a table.
@code, @samp, @var, and `---'
.............................
   * Use `@code' around Lisp symbols, including command names. For
     example:
          The main function is @code{vc-next-action}, ...
   * Avoid putting letters such as `s' immediately after an `@code'.
     Such letters look bad.
   * Use `@var' around meta-variables.  Do not write angle brackets
     around them.
   * Use three hyphens in a row, `---', to indicate a long dash.  TeX
     typesets these as a long dash and the Info formatters reduce three
     hyphens to two.
Periods Outside of Quotes
.........................
   Place periods and other punctuation marks *outside* of quotations,
unless the punctuation is part of the quotation.  This practice goes
against convention, but enables the reader to distinguish between the
contents of the quotation and the whole passage.
   For example, you should write the following sentence with the period
outside the end quotation marks:
     Evidently, `au' is an abbreviation for ``author''.
since `au' does *not* serve as an  abbreviation for `author.' (with a
period following the word).
Introducing New Terms
.....................
   * Introduce new terms so that a user who does not know them can
     understand them from context; or write a definition for the term.
     For example, in the following, the terms "check in", "register" and
     "delta" are all appearing for the first time; the example sentence
     should be rewritten so they are understandable.
          The major function assists you in checking in a file to your
          version control system and registering successive sets of
          changes to it as deltas.
   * Use the `@dfn' command around a word being introduced, to indicate
     that the user should not expect to know the meaning already, and
     should expect to learn the meaning from this passage.
@pxref
......
   Absolutely never use `@pxref' except in the special context for
which it is designed: inside parentheses, with the closing parenthesis
following immediately after the closing brace.  One formatter
automatically inserts closing punctuation and the other does not.  This
means that the output looks right both in printed output and in an Info
file, but only when the command is used inside parentheses.
Invoking from a Shell
.....................
   You can invoke programs such as Emacs, GCC, and GAWK from a shell.
The documentation for each program should contain a section that
describes this.  Unfortunately, if the node names and titles for these
sections are all different, readers find it hard to search for the
section.
   Name such sections with a phrase beginning with the word
`Invoking ...', as in `Invoking Emacs'; this way users can find the
section easily.
ANSI C Syntax
.............
   When you use `@example' to describe a C function's calling
conventions, use the ANSI C syntax, like this:
     void dld_init (char *@var{path});
And in the subsequent discussion, refer to the argument values by
writing the same argument names, again highlighted with `@var'.
   Avoid the obsolete style that looks like this:
     #include <dld.h>

     dld_init (path)
     char *path;
   Also, it is best to avoid writing `#include' above the declaration
just to indicate that the function is declared in a header file.  The
practice may give the misimpression that the `#include' belongs near
the declaration of the function.  Either state explicitly which header
file holds the declaration or, better yet, name the header file used
for a group of functions at the beginning of the section that describes
the functions.
Bad Examples
............
   Here are several examples of bad writing to avoid:
     If you are working with other people, it assists in coordinating
     everyone's changes so they do not step on each other.
It is not clear what `it' refers to.
     SCCS, RCS and other version-control systems all perform similar
     functions in broadly similar ways (it is this resemblance which
     makes a unified control mode like this possible).
Say, "... makes a unified interface such as VC mode possible."
     When you are done editing the file, you must perform a
     `@dfn'{check in}.
Say, " ... you must `@dfn'{check in} the new version." That flows
better.
And Finally ...
...............
   * Pronounce TeX as if the `X' were a Greek `chi', as the last sound
     in the name `Bach'.  But pronounce Texinfo as in `speck':
     `teckinfo'.
   * Write notes for yourself at the very end of a Texinfo file after
     the `@bye'.  None of the formatters process text after the `@bye';
     it is as if the text were within `@ignore' ... `@end ignore'.

Inserting Permissions
=====================
   In a Texinfo file, the first `@ifinfo' section usually begins with a
line that says what the file documents.  This is what a person reading
the unprocessed Texinfo file or using the advanced Info command `g *'
sees first.  *note Advanced Info commands: (info)Expert, for more
information. (A reader using the regular Info commands will usually
start reading at the first node and skip this first section, which is
not in a node.)
   In the `@ifinfo' section, the summary sentence should be followed by
a copyright notice and then by the copying permission notice.  One of
the copying permission paragraphs is enclosed in `@ignore' and `@end
ignore' commands.  This paragraph states that the Texinfo file can be
processed through TeX and printed, provided the printed manual carries
the proper copying permission notice.  This paragraph is not made part
of the Info file since it is not relevant to the Info file; but it is a
mandatory part of the Texinfo file since it permits people to process
the Texinfo file in TeX.
   In the printed manual, the Free Software Foundation copying
permission notice follows the copyright notice and publishing
information and is located within the region delineated by the
`@titlepage' and `@end titlepage' commands.  The copying permission
notice is exactly the same as the notice in the `@ifinfo' section
except that the paragraph enclosed in `@ignore' and `@end ignore'
commands is not part of the notice.
   To make it simple to copy the permission notice into each section of
the Texinfo file, the complete permission notices for each section are
reproduced in full below.
   Note that you may need to specify the correct name of a section
mentioned in the permission notice.  For example, in `The GDB Manual',
the name of the section referring to the General Public License is
called the "GDB General Public License", but in the sample shown below,
that section is referred to generically as the "General Public License".
