`@node' Line Requirements
-------------------------
Here are several requirements for `@node' lines:
* All the node names for a single Info file must be unique.
Duplicates confuse the Info movement commands. This means, for
example, that if you end every chapter with a summary, you must
name each summary node differently. You cannot just call each one
"Summary". You may, however, duplicate the titles of chapters,
sections, and the like. Thus you can end each chapter in a book
with a section called "Summary", so long as the node names for
those sections are all different.
* A pointer name must be the name of a node.
The node to which a pointer points may come before or after the
node containing the pointer.
* @-commands used in node names generally confuse Info, so you
should avoid them. This includes punctuation characters that are
escaped with a `@', such as `@' and `{'. For a few rare cases
when this is useful, Texinfo has limited support for using
@-commands in node names; see Note:Pointer Validation.
Thus, the beginning of the section called `@chapter' looks like
this:
@node chapter, unnumbered & appendix, makeinfo top, Structuring
@comment node-name, next, previous, up
@section @code{@@chapter}
@findex chapter
* You cannot use parentheses in node names, because a node name such
as `(foo)bar' is interpreted by the Info readers as a node `bar'
in an Info file `foo'.
* Unfortunately, you cannot use periods, commas, colons or
apostrophes within a node name; these confuse TeX or the Info
formatters.
For example, the following is a section title:
@code{@@unnumberedsec}, @code{@@appendixsec}, @code{@@heading}
The corresponding node name is:
unnumberedsec appendixsec heading
* Case is significant.
