+ * Comment:
+ * CML is the abbreviation of Coupled-Map Lattice that is a model of
+ * complex systems, proposed by a physicist[1,2].
+ *
+ * Similar models are summaried as follows:
+ *
+ * Value Time Space
+ * Coupled-Map Lattice cont. discrete discrete
+ * Celluar Automata discrete discrete discrete
+ * Differential Eq. cont. cont. cont.
+ *
+ * (But this program uses a parameter: hold-rate to avoid very fast changes.
+ * Thus time is rather continuous than discrete.
+ * Yes, this change to model changes the output completely.)
+ *

+ * 1. Kunihiko Kaneko, Period-doubling of kind-antikink patterns,
+ * quasi-periodicity in antiferro-like structures and spatial
+ * intermittency in coupled map lattices -- Toward a prelude to a

+ * Lattices (Wiley, 1993).
+ *
+ * About Parameter File:
+ * I assume that the possible longest line in CMP parameter file is 1023.
+ * Please read CML_save_to_file_callback if you want know details of syntax.
+ *
+ * Format version 1.0 starts with:
+ * ; This is a parameter file for CML_explorer
+ * ; File format version: 1.0
+ * ;
+ * Hue
+ *
+ * The old format for CML_explorer included in gimp-0.99.[89] is:
+ * ; CML parameter file (version: 1.0)
+ * ; Hue
+ *
+ * (This file format is interpreted as format version 0.99 now.)
