documentation.
\end{Description}
\begin{Usage}
\begin{verbatim}
help.start(gui = "irrelevant", browser = getOption("browser"),
           remote = NULL)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{gui}] just for compatibility with S-PLUS.
\item[\code{browser}] the name of the program to be used as hypertext
browser. It should be in the PATH, or a full path specified.

\item[\code{remote}] A character giving a valid URL for the \file{\$R\_HOME}
directory on a remote location.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
All the packages in the known library trees are linked to directory
\file{.R} in the per-session temporary directory.  The links are
re-made each time \code{help.start} is run, which should be done
after packages are installed, updated or removed.

If the browser given by the \code{browser} argument is different from
the default browser as specified by \code{options("browser")}, the
default is changed to the given browser so that it gets used for all
future help requests.
\end{Details}
\begin{Note}\relax
There is a Java-based search facility available from the HTML page
that \code{help.start} brings up.  Should this not work, please
consult the \sQuote{R Installation and Administration} manual which is
linked from that page.
