7. Directories

For simple projects that distribute all files in the same directory it is enough to have a single ‘Makefile.am’ that builds everything in place.

In larger projects it is common to organize files in different directories, in a tree. For instance one directory per program, per library or per module. The traditional approach is to build these subdirectories recursively: each directory contains its ‘Makefile’ (generated from ‘Makefile.am’), and when make is run from the top level directory it enters each subdirectory in turn to build its contents.
