I would like to have small "main" programs at the end of each module I
write, which basically run just that module for testing and as

part of larger code which is using these modules, or to make separate
test programs for each module.
The two ways I think of now, are using the C preprocessor,
#ifdef TEST
#endif
You can set environment variables from the command line with most
compilers.
The other is D lines, I believe inherited by most current compilers
from a DEC feature. At least gfortran, g95, and ifort have it.
Instead of using C for a comment, you use D in column one for
debugging (or testing) code, with a compile time option to
treat it as a comment or code.
