EFF_EXP(1)                       RPN UTILITY                        EFF_EXP(1)
NAME
        eff_exp - delete an etagere experiment.

USAGE
        eff_exp experiment_name

DESCRIPTION
        eff_exp is a command of  the etagere system (environnement de  travail
automatise de gestion  d'experiences avec  RCS) used to  delete an  experiment
from the RCS  sub-directory (i.e.,  remove a  revision from  the rcs  revision
tree). An experiment located at  a node point in  the revision tree cannot  be
deleted by eff_exp.  In other words, an experiment cannot be erased if it  has
been used as the starting point to more than one experiment.

EXAMPLE

        We have the following experiment tree:

                          _______________
                         |               |
                         |     base      |
                         |_______________|
                                 |
                          _______|_______
                         |               |
                         |  experiment01 |
                         |_______________|
                                 |
    _______________       _______|_______       ________________
   |               |     |               |     |                |
   | experiment02-a|-----|  experiment02 |-----| experiment02-b |
   |_______________|     |_______________|     |________________|
                                 |
                          _______|_______
                         |               |
                         |  experiment03 |
                         |_______________|

The command
             eff_exp experiment02

will result in an  error message because  it serves as  the starting point  to
more than one experiment.  However,  all the other experiments can be  deleted
from the revision tree.  For example,

              eff_exp experiment01

will delete  experiment01 from  the  revision tree  and  will create  all  the
necessary links between base and experiment02.
