include/TODO

+
+Some of the xxx_2.H or xxx_3.H variants can be easily removed. I found that to be the case for C.CHAVE.H, in toroid, its variables are not used. Then, C.CHAVE_2.H can be renamed to  C.CHAVE.H
+
+Some of the xxx_2.H or xxx_3.H variants are easy to change to xxx.H. For instance grep C.RIGID_2.H in [pathTo]/zgoubi/*f: it yields a handful of routines, in which DP can be changed to whatever convenient and then DPPP to DP, and then C.RIGID_2.H to C.RIGID.H.
+
+In some cases, TBD, it may require a little more work to remove, if useful, the xxx_2.C or xxx_3.C variant. It seems it is the case for instance for C.AIM.H.
