    GUIDE TO FURTHER DOCUMENTATION

    The overview and examples above are intended just to get you started.
    To use the software to do real work, you will probably need to refer
    to the detailed documentation on the commands (and on the features
    common to more than one command) that is contained in the files ending
    with ".doc".  These files are found in the various sub-directories,
    and are also all linked to from the 'doc' directory.  For quick
    reference, all commands print a brief summary of the command syntax
    when they are invoked with no arguments.

    In the syntax descriptions used, the characters "[" and "]" enclose
    parts of the command that are optional, "{" and "}" enclose optional
    parts that can be repeated, and "|" separates alternatives.  Except
    for the command name (or other obvious keywords), the words in the
    syntax descriptions are descriptive of what is to be entered, except
    that words in quotes are to be entered literally (without the quotes).

    The ".doc" files present in the various directories are listed below,
    with the more important files marked by "*".  Programs listed as
    "xxx-something" are generic, with "xxx" being replaced by the name of
    an application (eg, "net", "gp", or "mix").  In some cases, further
    documentation is available under the specific name.

    The file index.html is a hypertext index to this documentation.  It
    can be accessed using a Web browser (eg, netscape), by opening
    index.html as a local file (which will probably require giving its
    full path name).  The index.html file must reside in the 'doc'
    directory for this software, so that relative references will work
    correctly.  The files accessed this way are .html files derived from
    the .doc files.  The content is identical, except that references to
    other .doc files have been converted into hypertext links that you can
    follow with the browser.

    The 'doc' directory also contains comments on the various software
    releases, in files of the form 'Release.YYYY-MM-DD.doc'.

    All the introductory documentation (including this) is collected into
    the 'manual' file, as plain text.  You can print all the documentation
    by going to the main directory for this software and issuing a command
    such as

      lpr doc/manual util/*.doc mc/*.doc dist/*.doc bvg/*.doc \
          net/*.doc gp/*.doc mix/*.doc dft/*.doc doc/Rel*.doc

    (or using whatever command other than 'lpr' you use to print text files).
    This will produce about 200 pages of paper.
