+"""Pickler class to extend the standard pickle.Pickler functionality
+
+The main objective is to make it natural to perform distributed computing on
+clusters (such as PySpark, Dask, Ray...) with interactively defined code
+(functions, classes, ...) written in notebooks or console.
+
+In particular this pickler adds the following features:
+- serialize interactively-defined or locally-defined functions, classes,
+  enums, typevars, lambdas and nested functions to compiled byte code;
+- deal with some other non-serializable objects in an ad-hoc manner where
+  applicable.
+
+This pickler is therefore meant to be used for the communication between short
+lived Python processes running the same version of Python and libraries. In
+particular, it is not meant to be used for long term storage of Python objects.
+
+It does not include an unpickler, as standard Python unpickling suffices.
