Putting a program together

This chapter explains, step by step, how to create a "real" program that meets GNU standards for a command-line interface. It also discusses how to create a program whose source is split into multiple files, and how to compile it, with or without the GNU utility make. Finally, it discusses how to create a code library, in case you write some useful functions that you want to share with other programmers.
