SYNOPSIS

explain [HELP_FILENAME]

DESCRIPTION

    >1 Help_File_Format
    >
    >This is a brief suggestion of how a help file is laid out. A line
    >that begins with a number marks the beginning of a topic. The text
    >on that line is the label for the topic.
    >
    >2 What_the_User_Sees
    >
    >On issuing the help command, the user sees the main topic printed out.
    >Following this, a list of the immediate subtopics is presented.
    >The user can proceed to a subtopic by typing its label.
    >
    >3 Sub_Sub_Topics
    >
    >The arrangement of topics is a little like the grouping of parentheses.
    >
    >2 Suggestions
    >
    >You might want to keep each subtopic short, certainly no more than
    >a page in length.

            Integrated into the GPF(General Purpose Fortran) format. The
            basic login remains the same, sans some utility routines
            that duplicated GPF routines; added the command --help
            and --version switches; allowed abbreviated case-insensitive
            topics.
