 \begin{verbatim}
 irisstartup
 irisstartup -shutup
 \end{verbatim}
 \paragraph{Description}
 
 We recommend that you keep the IRIS root directory on the permanent
 Matlab search path. Each time you wish to start working with IRIS, you
 run \texttt{irisstartup} form the command line. At the end of the
 session, you can run \href{config/irisfinish}{\texttt{irisfinish}} to
 remove IRIS subfolders from the temporary Matlab search path, and to
 clear persistent variables in some of the backend functions.
 
 The \href{config/irisstartup}{\texttt{irisstartup}} performs the
 following steps:
 
 \begin{itemize}
 \item
   Adds necessary IRIS subdirectories to the temporary Matlab search
   path.
 \item
   Removes redundant IRIS folders (e.g.~other or older installations)
   from the Matlab search path.
 \item
   Resets IRIS configuration options to default, updates the location of
   TeX/LaTeX executables, and calls
   \href{config/irisuserconfighelp}{\texttt{irisuserconfig}} to modify
   the configuration option.
 \item
   Associates the default IRIS extensions with the Matlab Editor. If they
   had not been associated before, Matlab must be re-started for the
   association to take effect.
 \item
   Prints an introductory message on the screen unless
   \texttt{irisstartup} is called with the \texttt{-shutup} input
   argument.
 \end{itemize}
