We include here a brief summary for quick reference. The echelle package is hierarchically organised from low-level commands (level 0) to high-level commands (level 3). The organization is a result of the following classification: <P> <UL> <LI>Level 0. <BR> Apart from the level 0 command <TT>LOAD/ECHELLE</TT>, the user will make seldom use of level 0 commands. All parameters of these commands must be provided on the command line. The user may use these commands to benefit from options non available from higher level commands. <LI>Level 1. <BR> Level 1 commands perform the individual steps of the reduction. Parameters may be provided on the command line (thus updating the echelle keywords) or will be read from the echelle keywords (set by command <TT>SET/ECHELLE</TT>). Level 1 command enable to check individual steps of the reduction. <LI>Level 2. <BR> Level 2 commands perform high level steps of the reduction. The level 2 set of commands is self-consistent and enables to perform a complete reduction, with the optional use of verification lower level commands <TT>PLOT/ECHELLE, PLOT/IDENT, LOAD/IDENT, PLOT/RESIDUAL, LOAD/ECHELLE</TT>. Apart from method keywords and input/output images, no parameter value is required on the command line, all keywords being updated by <TT>INIT/ECHELLE</TT> and <TT>SET/ECHELLE</TT> commands. <LI>Level 3. <BR> The higher level 3 includes only two very general commands. The <TT>SET/CONTEXT</TT> initializes echelle keyword values and <TT>TUTORIAL/ECHELLE</TT> provides a demonstration of the package. </UL> <P> <BR> <DIV ALIGN="CENTER"><A NAME="7486"> </A> <TABLE>
