This tree is not part of eCos itself: it is the
directory in which eCos end users write their own
applications.
Example applications and their
Makefile are located in the component
repository, in the directory
BASE_DIR/examples.
There is no imposed format on this directory, but there
are certain compiler and linker flags that must be used to
compile an eCos application. The basic set of flags is shown
in the example Makefile, and additional
details can be found in Chapter 26.
