+ * Disabling features
+ * ------------------
+ *
+ * As explained in the [README](https://github.com/laurencelundblade/QCBOR#disabling-features), qcbor
+ * provides options to disable some features and reduce code size.
+ * Just add them to `CFLAGS` in the application `Makefile` or directly to the command line.
+ * For example, in the command line:
+ *
+ * ```
+ * CFLAGS="-DQCBOR_DISABLE_INDEFINITE_LENGTH_STRINGS" BOARD=samr21-xpro make -C tests/pkg_qcbor
+ * ```
+ *
