	#                        make it faster. Level 3 is the most 
	#                        optimization available.
	#   -Og                : Enables optimizations that do not interfere
	#                        with debugging. It should be the

	#                        standard edit-compile-debug cycle.

	#                        as well.

	#                        the bounds of the array every time an array
	#                        element is accessed.
	#                        This substantially slows down a program 
	#                        using it, but is a very useful way to find 
	#                        bugs related to arrays.
	#   -fbacktrace        : If the program crashes, a backtrace will be
	#                        produced if possible.
	#   -Wall              : gfortran will generate warnings about many 
	#                        common sources of bugs.
	#   -Wpedantic         : Generate warnings about language features 
	#                        that are supported by gfortran but are not 
	#                        part of the official Fortran 95 standard. 
	#   -Wextra            : This enables some extra warning flags that 
	#                        are not enabled by -Wall. Note, 
	#                        -Wunused-parameter (part of -Wextra) has a
