When you install an Info file onto your system, you can use the program
install-info to update the Info directory file dir.
Normally the makefile for the package runs
after copying the Info file into its proper installed location.
In order for the Info file to work with
install-info, you include
@end direntry in the Texinfo source
@direntry to specify the menu entries to add to the
Info directory file. Use
@dircategory to specify a category
for the manual, which determines which part of the Info directory to
put it in. See Directory Category.
Here is how these commands are used in this manual:
@dircategory Texinfo documentation system @direntry * Texinfo: (texinfo). The GNU documentation format. * install-info: (texinfo)Invoking install-info. … … @end direntry
Here’s what this produces in the Info file:
INFO-DIR-SECTION Texinfo documentation system START-INFO-DIR-ENTRY * Texinfo: (texinfo). The GNU documentation format. * install-info: (texinfo)Invoking install-info. … … END-INFO-DIR-ENTRY
install-info program sees these lines in the Info file, and
that is how it knows what to do.
Always use the
@dircategory commands near
the beginning of the Texinfo input, before the first
command. If you use them later on in the input,
will not notice them.
install-info will automatically reformat the description of the
menu entries it is adding. As a matter of convention, the description
of the main entry (above, ‘The GNU documentation format’) should
start at column 32, starting at zero (as in
what-cursor-position in Emacs). This will make it align with
most others. Description for individual utilities best start in
column 48, where possible. For more information about formatting see
the ‘--calign’, ‘--align’, and ‘--max-width’ options in
If you use
@dircategory more than once in the Texinfo source,
each usage specifies the ‘current’ category; any subsequent
@direntry commands will add to that category.
Each ‘Invoking’ node for every program installed should have a
@direntry. This lets users easily find the
documentation for the different programs they can run, as with the
