COMMAND NAME:

        HELP

USAGE:

        HELP

        HELP is a file based information retrieval system for
information concerning the usage of an application's commands.

        HELP by itself offers you a popup menu of commands available
in the application.  Selecting an entry will provide further
information on the selected entry, if available.

        HELP information may also be categorized by subjects.
If any information refers to subjects which match the requested subject,
it is offered via a popup menu for viewing.

        Finally, HELP information may also be searched by pattern content;
note that this is the slowest method.

        Any of the fields in angle brackets <> may contain the
usual pattern matching characters: *, ?, [], [^].

EXAMPLES:

        Help information can be displayed using commands similar to
the following:

        HELP help
        provide information on the command "help"

        HELP SUBJECT
        list out all available subjects

        HELP SUBJECT help
        provide information on any topic referencing "help";
select the desired "help" topic

        HELP APROPOS help
        provide information on any topic containing the substring "help";
select the desired "help" topic

ADDITIONAL INFORMATION:

        The HELP files come from a set of directories
determined by the application.
Each documented command has an associated file with a ".hlp" extension.
Miscellaneous other files which are not directly related to a command
also have the ".hlp" extension.

        In addition, the HELP information may include a list
of related subjects which are referenced within the text;
these are stored in a file having a ".sub" extension.
