+     "The decision-table package allows for an easy way to generate decision
+tables in the Decision Model and Notation (DMN) format.  This package ensures
+consistency in the tables (i.e., fontsize), and is thus a better alternative
+to inserting tables via images.
+
+The decision-table package adds the @code{\\dmntable} command, with which
+tables can be created.  This command expands into a tabular, so it can be used
+within a @code{table} or @code{figure} environment.  Furthermore, this allows
+labels and captions to be added seamlessly.  It is also possible to place
+multiple DMN tables in one table/figure environment.")
