# Writing for the HTML Help System:

      Contributions are very welcome. If you wish to make a contribution to
      the HTML Help System, please contact the maintainer:

## The structure of the \help directory:

      \help\index.htm
        Lists the help languages installed on the system.
        Loaded automatically if LANG is not set to an available language
        and English (EN) not installed.
      \help\%LANG%\index.htm
        HELP will load this by default. %LANG% is the language selected by
        setting the LANG environment variable. If LANG isn't set, EN is assumed.
      \help\%LANG%\help.htm
        HELP will load this when the user presses F1 or clicks on
        "Help on Help".
      \help\docinfo\bi\nls\%LANG%.bi
        Stores bookshelf files, for use with Aitor's bookshlf tool, to
        create the language index (\help\index.htm).

## Creating compressed help files:

      You should use for your compressed file set a name such as:
        \help\...\[name]\[name].zip
      If you wish to compress your help files, they should be in the
      zip format. They should have the same filename as the directory
      they are stored in, and the zip extension. For instance:
        \help\en\myhelp\myhelp.zip
      The index.htm can be inside the zip file, but help and bookshlf
      will both work better if it is not.
      Directory structures are allowed within the zip file. However,
      encryption and some of the older and more obscure compression
      methods are not supported.

## Creating modified versions of the help files:

      Use a distinct title on the title page (often index.htm) in any
      modified versions. This is to avoid any confusion or conflicts,
      and most importantly, is necessary under the
      GNU Free Documentation License part 4A.
      In addition to changing the title, please update the history, list of
      authors etc, in accordance with section 4 of the
      GNU Free Documentation License.
      If the file set is meant to describe a new or modified package, or if
      the file set undergoes a fundamental change (e.g. a translation), then
      it is best to use a distinct subdirectory name, as explained in "The
      structure of the \help directory" above. This is simply a matter of
      doing a find and replace on the subdirectory name in index.htm, and is
      well worth it.
      For example, a streamlined version of the "hhstndrd" file set might be
      called "hhmicro". This would be the name of the subdirectory, and the
      title in index.htm might be:
        FreeDOS Hilfe (hhmicro 1.0)
      It is reasonable to change only the version number (rather than the
      name and directory "hhmicro") when releasing updates.

## Creating or adding new files:

      It is advised that the following license message be put at the end of
      any new help files (unless it is going to be a stand alone file, not
      included in a help file set):

        ...
        <hr>
        <address>

        <b>Copyright &copy; 2008
        <a href="mailto:myemail@address.com">My name</a></b><br>
        This file forms part of The FreeDOS HTML Help Documentation, and is
        covered under its terms, see:
        <a href="../index.htm">index.htm</a>

        </address>
        </body>
        </html>

      Providing an email is entirely optional; if you load your help files on
      to a website, then email addresses can be subjected to spamming.
      The terms are the GNU Free Documentation License.

## Editing a file stored in a zip:

      You may wish to unzip the html files so that they can be read with
      another browser, or to edit them. Zip files usually take priority over
      uncompressed files; if you want to make sure that help reads an edited,
      uncompressed version of a file, you should replace or delete the
      original version inside that zip.

## Testing help files:

      The reference browsers for testing help files are:
        * the FreeDOS HTML Help Viewer (help.exe)
        * Netscape Navigator.

## Creating tables:

      Unfortunately, help does not support table tags. Use the preformatting
      tags <pre> </pre> for tables of information.

## General tips:

      Press F5 or Ctrl+R to refresh the file being displayed by Help.The
      effects of changes to the file can be seen immediately. Useful when
      editing help files in a windows-type environment.
      To use HTML Help Viewer to view files that aren't yet integrated into
      the file set, the help path override switch can be used:
        help /O[drive:][path]filename[.htm]
      or if relative to the /HELP folder:
        help /L[subdirs]filename[.htm]
