 the \function{getcontext()} and \function{setcontext()} functions:
 
 \begin{funcdesc}{getcontext}{}
-  Return the current context for the active thread.                                          
+  Return the current context for the active thread.
 \end{funcdesc}            
 
 \begin{funcdesc}{setcontext}{c}
-  Set the current context for the active thread to \var{c}.                                          
+  Set the current context for the active thread to \var{c}.
 \end{funcdesc}  
 
 Beginning with Python 2.5, you can also use the \keyword{with} statement
-to temporarily change the active context. For example the following code
-increases the current decimal precision by 2 places, performs a
-calculation, and then automatically restores the previous context:

+\begin{funcdesc}{localcontext}{\optional{c}}
+  Return a context manager that will set the current context for
+  the active thread to a copy of \var{c} on entry to the with statement
+  and restore the previous context when exiting the with statement.

 The context that's active in the body of the \keyword{with} statement is
 a \emph{copy} of the context you provided to the \keyword{with}
