- * Optimization flags.
+ * Flags to customize the behaviour of libfirm.
  *
  * @author Christian Schaefer
+ *
+ * There are the following groups of flags:
+ * 1. Optimization flags.
+ *    a)  There is a flag, 'optimize' to turn on/off all optimizations.
+ *    b)  There are flags for each individual optimization.  Some flags turns
+ *        transformations in several algorithms on/off.
+ * 2. Normalization flags.
+ *    These flags steer transformations of the ir that improve it, as removing
+ *    dump Phi nodes (one predecessor, all preds are equal ...), Ids, Tuples ...
+ * 3. Verbosity flags.
+ *    a) Flags to steer the level of the information.
+ *    b) Flags to steer in which phase information should be dumped.
