Quoting from an HP web page:

"A C [and C++] program consists of one or more translation units, each
of which can be compiled separately. A translation unit consists of a
source file together with any headers and source files included by the
#include preprocessing directive. Each time the compiler is invoked, it
reads a single translation unit and typically produces a relocatable
object file."

Most of CGAL's demos/examples consist of only one translation unit.
