=head1 NAME

    shelves.pl

=head1 DESCRIPTION

    this script is used to script to provide virtualshelf management

=head1 CGI PARAMETERS

=over 4

=item C<modifyshelfcontents>

    if this script has to modify the shelve content.

=item C<shelfnumber>

    to know on which shelve this script has to work.

=item C<addbarcode>

=item C<op>

    op can be equals to:
        * modifsave to save change on the shelves
        * modif to change the template to allow to modify the shelves.

=item C<viewshelf>

    to load the template with 'viewshelves param' which allow to read the shelves information.

=item C<shelves>

    if equals to 1. then call the function shelves which add
    or delete a shelf.

=item C<addshelf>

    if the param shelves = 1 then addshelf must be equals to the name of the shelf to add.
