     ==============================
 
+checkpoint52e_post
+o first attempt to solve vertical advection (momemtum & T,S) Implicitly
+  for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
+o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
+  to work with implicit vertical advection and AB ;
+o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
+o update output (gad_calc_rhs.F changes affect truncation error) of exp:
+ front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
+checkpoint52e_pre
+
+o fix bug in impldiff when Nr=1 or Nr=2.
 o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
 o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
 o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
