=over 4
=item C<modifyshelfcontents>
If this script has to modify the shelf content.
=item C<shelfnumber>
To know on which shelf to work.
=item C<addbarcode>
=item C<op>
Op can be:
* modif: show the template allowing modification of the shelves;
* modifsave: save changes from modif mode.
=item C<viewshelf>
Load template with 'viewshelves param' displaying the shelf's information.
=item C<shelves>
If the param shelves == 1, then add or delete a shelf.
=item C<addshelf>
If the param shelves == 1, then addshelf is the name of the shelf to add.
