``better'' profilers from the classes presented, or reading the source
code for these modules.
-\begin{funcdesc}{run}{string\optional{, filename\optional{, ...}}}
+\begin{funcdesc}{run}{command\optional{, filename}}
This function takes a single argument that has can be passed to the
\keyword{exec} statement, and an optional file name. In all cases this
\end{funcdesc}
+\begin{funcdesc}{runctx}{command, globals, locals\optional{, filename}}
+This function is similar to \function{profile.run()}, with added
+arguments to supply the globals and locals dictionaries for the
+\var{command} string.
+\end{funcdesc}

Analysis of the profiler data is done using this class from the

-------
+- Added global runctx function to profile module
+
- Add hlist missing entryconfigure and entrycget methods.
- The ptcp154 codec was added for Kazakh character set support.
