To install grocer:

1) unzip the file grocer_1.0_for_sci3.0.zip in scilab directory. This operation:
- creates a directory macros/grocer in scilab directory: these are grocer .sci files
- creates a directory macros/grocer in scilab directory: these are grocer help files
- replaces the scilab.star in your scialb directory. If you have yourself modified your scilab?.star, the you
Will have to enter these modifications again (think to save these modficiations somewhere before installing grocer

2) run scilab. here is what will appear on screen:

The operation will take a few seconds (but less than a minute on sufficinetly recent computers)

3) the next time you will run scilab, then the following will appear on screen ;

4) at the pompt, write hendryericsson() and enter. Then scilab should open 2 graphic windows and display the following:
