### Description

Start the hypertext system for help. Use this system to browse the contents of available packages, and to find and display help files by topic.

### Usage

    help.start(update = FALSE, gui = "irrelevant", browser = getOption("browser"),
        remote = NULL)

### Arguments

update | a logical value. If TRUE, the file packages.html under "<home>/doc/html/" is updated before the local hypertext help system starts. The default is FALSE.
gui | not used currently. Present for compatibility with S+.
browser | Defines the browser to start the URL. Passed to browseURL().
remote | a character string specifying the remote HTTP server and port number. If NULL (the default), the local HTTP server is used to launch the hypertext help system.

### Details

This function starts a hypertext help system on a local or a remote HTTP server. If remote is NULL, startDynamicHelp() is called to start a local HTTP server. The local server is fixed as http://127.0.0.1:<port>.
The URL to start for the hypertext help system is set as <HTTP_server:port>/doc/html/index.html. The function browseURL() is called to start this URL.
