 The \module{pickle} module provides the
 following functions to make this process more convenient:

 \class{Pickler} objects define one (or two) public methods:
 
-\begin{methoddesc}[Pickler]{dump}{object}
-Write a pickled representation of \var{object} to the open file object
+\begin{methoddesc}[Pickler]{dump}{obj}
+Write a pickled representation of \var{obj} to the open file object
 given in the constructor.  Either the binary or \ASCII{} format will
 be used, depending on the value of the \var{bin} flag passed to the
 constructor.
