    Installation of the Objective-J tools to $INSTALL_DIR is almost complete!
    
    Several environment variables must be set:
    
    - PATH should include $INSTALL_DIR/bin:

        export PATH=\$PATH:$INSTALL_DIR/bin
        
        (currently: $PATH)

    - OBJJ_HOME should be set to $INSTALL_DIR/share/objj:

        export OBJJ_HOME=$INSTALL_DIR/share/objj
        
        (currently: $OBJJ_HOME)
    
    - STEAM_BUILD should be set to the build directory of your choice (e.x. $HOME/objj_build):

        export STEAM_BUILD=$HOME/objj_build
        
        (currently: $STEAM_BUILD)
