// rootlogon.C
// ===========
//
// This file is the startup script ("autoexec.bat") executed when root is
// started. The definition which file to start is done in ".rootrc".
// There are three files which are automatically processed by root at
// startup: A systemwide .rootrc, one in your home directory and one
// in the current directory.
// So rootlogon.C is correctly executed if your start root from your
// Mars directory.
//
// The script setupts some small environmental things and makes
// sure that the Mars shared object (libmars.so) is loaded. This shared
// object gives you access to all Mars features from within the root
// interpreter.
//
// If libmars.so is not found in the current directory we search in the
// directory given in "MARSSYS" environment variable.
