A Simple Makefile Example

**F90_SIMPLE** is a simple example of how a makefile can be
used to manage a set of FORTRAN90 files.

The underlying task is to approximate the integral of a
function **F(T)** using the midpoint rule. The program
to do this is broken up into three FORTRAN90 files:

- f90_simple.f90 contains the main program, which tries the midpoint rule three times, each time using more intervals.
- midpoint.f90 carries out the midpoint rule to approximate the integral of a function.
- f.f90 evaluates the function whose approximate integral is desired.

- makefile contains the makefile for managing these files.
- f90_simple_output.txt the output file.
