+// Macro: NDNBOOST_IOSTREAMS_DEFINE_FILTER_STREAM(name_, chain_type_, default_char_)
+// Description: Defines a template derived from std::basic_streambuf which uses
+// a chain to perform i/o. The template has the following parameters:
+// Mode - the i/o mode.
+// Ch - The character type.
+// Tr - The character traits type.
+// Alloc - The allocator type.
+// Access - Indicates accessibility of the chain interface; must be either
+// public_ or protected_; defaults to public_.
+// Macro parameters:
+// name_ - The name of the template to be defined.
+// chain_type_ - The name of the chain template.
+// default_char_ - The default value for the char template parameter.
+//
