For documenting purposes the model description can be provided with
comments, which have two different forms. The first form is
a single-line comment, which begins with the character # and
extends until end of line. The second form is a comment sequence,
which is a sequence of any characters enclosed between /* and
*/.
Examples
set s{1..10}; # This is a comment
/* This is another comment */
Comments are ignored by the model translator and can appear anywhere in the model description, where white-space characters are allowed.
