 == Description  ==
 
 This patch to enable the core support of BDY for TOP passive tracers with NEMO v3.6 (tested with r10254).
-Note that in this patch, routines that provide to initialization/reading of Boundary conditions (trcbc.f90) were also updated.

+Code is contained in the attached tarball and it consists of modified files wrapped in the classic "MY_SRC" folder to be added in NEMO configuration.
+These files have to be unpacked in the MY_SRC folder of your configuration in order to be used.

+''REMINDER'': MY_SRC contains user modified versions of NEMO routines or new pieces of code that are used at compilation time to supersede at original ones.
 
 Note that '''namelist_top_ref''' has to be modified by the user in <NEMODIR>/NEMOGCM/CONFIG/SHARED according to the description above (or the sample file provided in the tarball).
