This is a simple test of the board LED driver at
`nuttx/drivers/leds/userled_*.c`.
+## `libtest` Static Library Test
+
+This example illustrates how you may create a static library. It does the
following:
+
+It creates a static library called libtest.a that contains an object that
provides the symbol library_test().
+
+At adds the library as an EXTRA_LIB in the build
+
+EXTRA_LIBS += -ltest
+E XTRA_LIBPATHS += -L$(APPDIR)/examples/libtest
+
+And optionally, it can be configured to:
+
+Generate a built-in command that can be executed by NSH. This command logic
links with the symbol library_test() that will provided by the libtest.a static
library.
