DESCRIPTION
The hyperhelp 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 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 wid-
get. 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 available
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.

anchorname or both may be empty. If topicname is empty, the current topic is assumed. If anchorname is empty, the top of the docu-
ment 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.
