@subheading Goals

The @file{trunk/Scripts/Functions/Help/Backends} directory structure
organizes documentation backends used by @code{help} functionality of
@command{centos-art.sh} script.

@subheading Description

Documentation backends are organized inside directories. There is one
directory for each documentation backend available. Inside these
directories, actions related to documentation are implemented by mean
of shell functions. There is one shell function for each documentation
action (e.g., reading, editing, updating output, etc.). Optionally,
other shell functions might be added to backup documentation actions
functionalities.

Documentation backends use template files to build language-specific
documentation manual. Template files related to documentation backends
are stored in a directory name @file{Templates/LANG} inside the
backend directory. In this location, @var{LANG} is a variable
containing the locale information the documentation manual is built on
(e.g., en_US, es_ES, fr_FR, de_DE, etc.). Inside the
@file{Template/LANG} directory, it is organized the documentation
structure used as base to build new language-specific documentation
manuals (e.g., each time a new documentation entry is created for the
repository, a template is taken from here to initiate the section
structure and give order to it). The specific organization of
documentation structure depends on the backend itself.

Inside backend directories, shell functions must have the same
structure in their names. The name structure used by shell functions
here is: @code{suffix_funcname.sh}, were @code{suffix} is the name of
the directory backend in lowercase and @code{funcname} is the name of
the function. Assuming, both @samp{texinfo} and @samp{docbook}
backends have been already implemented, they must have a structure
similar to the following:

@verbatim
trunk/Scripts/Functions/Help/Backends
|-- Docbook
|   |-- Templates
|   |   |-- en_US
|   |   `-- ...
|   |-- docbook_editEntry.sh
|   |-- docbook_updateOutputFiles.sh
|   `-- ...
`-- Texinfo
    |-- Templates
    |   |-- en_US
    |   `-- ...
    |-- texinfo_editEntry.sh
    |-- texinfo_updateOutputFiles.sh
    `-- ...
@end verbatim
