+%% These functions are a compromise in the same vein as the use of the
+%% process dictionary in diameter_gen.hrl in generated codec modules.
+%% Instead of rewriting the entire dictionary generation to pass
+%% encode/decode options around, the calling process sets them by
+%% calling setopts/1. At current, the only option is whether or not to
+%% decode binaries as strings, which is used by diameter_types.
