   === Differences explaining the differences between the trunk and the tag 196 : ===
+  * In tag 196, when IMPOSE_VEG is activated veget is not calculated by the subroutine slowproc_veget. So as we have veget=veget_max, no fraction of bare soil is calculated. 
+  * In trunk (rev [947]), veget(:,1) is replaced by tot_frac_bare and slowproc_veget is called whatever the case. So a fraction is always calculated even in IMPOSE_VEG. This modification implies a modification of the value of z0 (and albedo). To have the same results, a call to slowproc_veget should be added in the tag version of slowproc  :

+       !Config Desc  = Height for all vegetation types

+       !Config Help  = The height used in the 0dim mode. The values should be found
+       !Config         in the restart file. The new values of height will be computed anyway
+       !Config         at the end of the current day. The need for this variable is caused
+       !Config         by the fact that the model may stop during a day and thus we have not

+This line lets ORCHIDEE to calculate a fraction of bare soil even in IMPOSE_VEG.
