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

WIDGET-SPECIFIC METHODS
pathName cget option
Returns the current value of the configuration option given by
option. Option may have any of the values accepted by the
hyperhelp command.
pathName configure ?option? ?value option value ...?
Query or modify the configuration options of the widget. If no
option is specified, returns a list describing all of the avail-
able options for pathName (see Tk_ConfigureInfo for information
on the format of this list). If option is specified with no
value, then the command returns a list describing the one named
option (this list will be identical to the corresponding sublist
of the value returned if no option is specified). If one or
more option-value 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. Option may have any
of the values accepted by the hyperhelp command.

the form topicname#anchorname. In this form, either topicname or
anchorname or both may be empty. If topicname is empty, the cur-
rent topic is assumed. If anchorname is empty, the top of the
document is assumed

Display html file href. Href may be optionally be of the form
filename#anchorname. In this form, either filename or anchorname
or both may be empty. If filename is empty, the current document
is assumed. If anchorname is empty, the top of the document is
assumed.
