+    \brief Converts a sequence to a Boost PP array whose elements are the elements of the sequence.
+
+    ...       = Variadic parameters.
+    
+    The first variadic parameter is required and is the sequence to convert.
+    
+    Further optional variadic parameters can be return type parameters. Return type
+    parameters allow each element in the sequence to be converted to a two-element
+    tuple where the first tuple element is the type and the second tuple element
+    is the element data.
+    
+    The BOOST_VMD_RETURN_NO_TYPE, the default, does not return the type as part of each
+    converted element but just the data. All of the rest return the type and data as the
+    two-element tuple. If BOOST_VMD_RETURN_TYPE is specified the specific type of the element
+    is returned in the tuple. If BOOST_VMD_RETURN_TYPE_ARRAY is specified an array type is 
+    returned if the element is an array, else a tuple type is returned if the element is a tuple, 
+    else the actual type is returned for non-tuple data. If BOOST_VMD_RETURN_TYPE_LIST is specified
+    a list type is returned if the element is a list, else a tuple type is returned if the element 
+    is a tuple, else the actual type is returned for non-tuple data. If BOOST_VMD_RETURN_TYPE_TUPLE 
+    is specified a tuple type is returned for all tuple-like data, else the actual type is returned 
+    for non-tuple data. If more than one return type optional parameter is specified the last one 
+    specified determines the return type.
+    
+    returns   = A Boost PP array. The sequence is empty the Boost PP array is an empty array.
+                If an optional return type other than BOOST_VMD_RETURN_NO_TYPE
+                is specified the type and the data of each element is
+                returned as the array element. Otherwise just the data
+                is returned as the array element, which is the default.
