    1111== Description  == 
    1212 
    1313This patch to enable the core support of BDY for TOP passive tracers with NEMO v3.6 (tested with r10254). 
    14 Note that in this patch, routines that provide to initialization/reading of Boundary conditions (trcbc.f90) were also updated. 
     14Note that in this patch, routines that provide to initialization/reading of all Boundary conditions (trcbc.f90) were also updated.

    1616''BDY schemes'' included in this version are the following (see trcbdy.F90):  
     
    5353== Usage walktrough  ==

    55 Code is contained in the attached tarball and it contains a set of modified files in the classic "MY_SRC" folder to be added in NEMO configuration. 
     55Code 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. 
     56These files have to be unpacked in the MY_SRC folder of your configuration in order to be used. 
     57 
     58''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. 
    5659 
    5760Note 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). 
    5861 
    59 A modified fortran data structure of namtrc was here developed to set the different boundary conditions of passive tracers, as in the following example : 
    60  
     62All boundary conditions are controlled within the namelist '''namtrc''' in namelist_top_(cfg/ref). 
     63A modified fortran data structure of namtrc was here developed to set the different boundary conditions of passive tracers, as in the following example of namelist_top_cfg : 
    6164 
    6265{{{ 
     
    7275/ 
    7376}}} 
     77where the new options relates to the provision of SURFACE (sbc), COASTAL (cbc), or  OPEN lateral Boundaries (obc) data for  sn_tracer(1)  named TRACER1. 
     78 
     79In '''namtrc_bc''' are provided the different boundary conditions for passive tracers, see the example below of namelist_top_cfg
