+------------
+27-Nov-2010:
 
-Assuming that nest_child/ and nest_parent/ are placed in pkg/
+driver:
+  split driver_nesting.F into "main.F" and "interpolation_p2c.F":
+  -use standard "gemake2" to build driver.
+  -change current dir + open & write to (proc specific) log file
+  -fix several problems (mostly in driver).
 
-code compiles for checkpoint_c61x on weddell.mit.edu for both parent and child setup via:
-../../../tools/genmake2 -of ../../../tools/build_options/linux_amd64_ifort_generic_mpi -mods '../code_parent ../code_nest_merged'
+parent & child pkgs:
+  -bring nesting code up-to date with MITgcm source code checkpoint62o
+  -move nesting code out of eeboot_minimal.F into nest_eeinit.F
+  -move nesting arrays out of GRID.h into new header file "NEST_SHARED.h"
+  -change current dir to "rankNN"
 
-and
+add parameter files and results of simplified Med_Gib nested set-up test
 
-../../../tools/genmake2 -of ../../../tools/build_options/linux_amd64_ifort_generic_mpi -mods '../code_child ../code_nest_merged'
+driver,parent & child: (29 Nov)
+  -parent & child send number of nesting steps to driver; stop if mismatch.
 
+code_nest_merged: ( 6 Dec)
+  finish merging of nested code into main code: remove the last 2 remaining
+  S/R: solve_for_pressure.F & obcs_calc.F
