... }. <EM>Topic</EM> may either be a topic name, in which case
the document associated with the topic should be in the
file <STRONG>helpdir</STRONG>/<EM>topic</EM>.html, or it may be of the form {<EM>name</EM>
<EM>file</EM>}. In the latter case, <EM>name</EM> is displayed in the
topic menu, and selecting the name loads <EM>file</EM>. If file
has a relative path, it is assumed to be relative to
helpdir.

<H2>DESCRIPTION</H2><PRE>
The <STRONG>hyperhelp</STRONG> command creates a shell window with a pulldown
menu showing a list of topics. The topics are displayed by
importing a HTML formatted file named <STRONG>helpdir</STRONG>/<EM>topic</EM>.html.
For a list of supported HTML tags, see <STRONG>scrolledhtml(n)</STRONG>.
</PRE>
<H2>METHODS</H2><PRE>
The <STRONG>hyperhelp</STRONG> command creates a new Tcl command whose name
is <EM>pathName</EM>. This command may be used to invoke various
operations on the widget. It has the following general
form:
<EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
<EM>Option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
mand. The following commands are possible for dialog widg-
ets:

<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
<EM>pathName</EM> <STRONG>cget</STRONG> <EM>option</EM>
Returns the current value of the configuration option
given by <EM>option</EM>. <EM>Option</EM> may have any of the values
accepted by the <STRONG>hyperhelp</STRONG> command.
<EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
Query or modify the configuration options of the
widget. If no <EM>option</EM> is specified, returns a list
describing all of the available options for <EM>pathName</EM>
(see <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
this list). If <EM>option</EM> is specified with no <EM>value</EM>, then
the command returns a list describing the one named
option (this list will be identical to the correspond-
ing sublist of the value returned if no <EM>option</EM> is
specified). If one or more <EM>option</EM> - <EM>value</EM> pairs are
specified, then the command modifies the given widget
option(s) to have the given value(s); in this case the
command returns an empty string. <EM>Option</EM> may have any
of the values accepted by the <STRONG>hyperhelp</STRONG> command.

<EM>topicname</EM> is empty, the current topic is assumed. If
<EM>anchorname</EM> is empty, the top of the document is assumed
