+
+This statement supports dynamic execution of Python code.  The first
+expression should evaluate to either a string, an open file object, or
+a code object.  If it is a string, the string is parsed as a suite of
+Python statements which is then executed (unless a syntax error
+occurs).  If it is an open file, the file is parsed until EOF and
+executed.  If it is a code object, it is simply executed.
+
+In all cases, if the optional parts are omitted, the code is executed
+in the current scope.  If only the first expression after \verb\in\ is
+specified, it should be a dictionary, which will be used for both the
+global and the local variables.  If two expressions are given, both
+must be dictionaries and they are used for the global and local
+variables, respectively.
+
+Note: dynamic evaluation of expressions is supported by the built-in
+function \verb\eval\.
