54 // <synopsis>
55 // <src>FunctionOrder</src> is used to provide an interface to an entity which
56 // has special fixed parameters (like dimension of Gaussian; oder of
57 // Polynomial).
58 // This is useful, for example, in implementinggeneric function factories.
59 //
60 // </synopsis>
61 //
62 // <example>
63 // See the <linkto class=FunctionHolder>FunctionHolder</linkto>
64 // class for a usage interface.
65 // </example>
66 //
67 // <motivation>
68 // Generically manipulatable parameters are important for Glish interface
69 // </motivation>

71 // <templating arg=T>
