Makefile lists each of the non-source files and how to compute it from other files

When you write a program, you should write a makefile for it, so that it is possible to use Make to build and install the program

This script is given arguments which describe the kind of machine and system you want to compile the program for

The configure script must record the configuration options so that they affect compilation
  • Makefile.in can be used by configure scripts to generate a working Makefile

Examine source files in the directory tree rooted at SRCDIR, or the current directory if none is given

Search the source files for common portability problems, check for incompleteness of 'configure.ac', and create a file 'configure.scan' which is a preliminary 'configure.ac' for that package
