+\section{Standard module \sectcode{dis}}	% If implemented in Python
+\stmodindex{dis}
+
+\label{module-dis}
+
+The \code{dis} module supports the analysis of Python byte code by
+disassembling it.  Since there is no Python assembler, this module
+defines the Python assembly language.  The Python byte code which
+this module takes as an input is defined in the file 
+\code{Include/opcode.h} and used by the compiler and the interpreter.
+
+Example: Given the function myfunc
+
+\bcode\begin{verbatim}
+def myfunc(alist):
+  return len(alist)
+\end{verbatim}\ecode
+
+the following command can be used to get the disassembly of myfunc:
+
+\begin{verbatim}
+>>> dis.dis(myfunc)
+          0 SET_LINENO          1
+
+          3 SET_LINENO          2
+          6 LOAD_GLOBAL         0 (len)
+          9 LOAD_FAST           0 (alist)
+         12 CALL_FUNCTION       1
+         15 RETURN_VALUE   
+         16 LOAD_CONST          0 (None)
+         19 RETURN_VALUE   
+\end{verbatim}
+
+The \code{dis} module defines the following functions:
+
+\renewcommand{\indexsubitem}{(in module dis)}
+
+% ---- 3.2. ----
+% For each function, use a ``funcdesc'' block.  This has exactly two
+% parameters (each parameters is contained in a set of curly braces):
+% the first parameter is the function name (this automatically
+% generates an index entry); the second parameter is the function's
+% argument list.  If there are no arguments, use an empty pair of
+% curly braces.  If there is more than one argument, separate the
+% arguments with backslash-comma.  Optional parts of the parameter
+% list are contained in \optional{...} (this generates a set of square
+% brackets around its parameter).  Arguments are automatically set in
+% italics in the parameter list.  Each argument should be mentioned at
+% least once in the description; each usage (even inside \code{...})
+% should be enclosed in \var{...}.
+
+\begin{funcdesc}{dis}{\optional{bytesource}}
+Disassemble the \var{bytesource} object. \var{bytesource} can denote
+either a class, a method, a function, or a code object.  For a class,
+it disassembles all methods.  For a single code sequence, it prints
+one line per byte code instruction.  If no object is provided, it
+disassembles the last traceback.
+\end{funcdesc}
+
+\begin{funcdesc}{distb}{\optional{tb}}
+Disassembles the top-of-stack function of a traceback, using the last
+traceback if none was passed.  The instruction causing the exception
+is indicated.
+\end{funcdesc}
+
+\begin{funcdesc}{disassemble}{code\optional{\, lasti}}
+Disassembles a code object, indicating the last instruction if \var{lasti}
+was provided.  The output is divided in the following columns:
+\begin{itemize}
+\item the current instruction, indicated as \code{-->},
+\item a labelled instruction, indicated with \code{>>},
+\item the address of the instruction,
+\item the operation code name,
+\item operation parameters, and
+\item interpretation of the parameters in parentheses.
+\end{itemize}
+The parameter interpretation recognizes local and global
+variable names, constant values, branch targets, and compare
+operators.
+\end{funcdesc}
+
+\begin{funcdesc}{disco}{code\optional{\, lasti}}
+A synonym for disassemble.  It is more convenient to type, and kept
+for compatibility with earlier Python releases.

+Implements \code{del TOS1[TOS]}.
+\end{funcdesc}

+\begin{funcdesc}{PRINT_EXPR}{}

+stack of blocks, denoting nested loops, try statements, and such.
+\end{funcdesc}
+
+\begin{funcdesc}{END_FINALLY}{}

+Creates a new class object.  TOS is the methods dictionary, TOS1
+the tuple of the names of the base classes, and TOS2 the class name.

+
+All of the following opcodes expect arguments.  An argument is two
+bytes, with the more significant byte last.

+Performs a boolean operation.  The operation name can be found
+in \code{cmp_op[opname]}.
+\end{funcdesc}
+
+\begin{funcdesc}{IMPORT_NAME}{namei}
+Imports the module \code{co_names[namei]}.  The module object is
+pushed onto the stack.  The current name space is not affect: for a

+modifies the name space.
+\end{funcdesc}
+
+\begin{funcdesc}{IMPORT_FROM}{namei}

+\begin{funcdesc}{SET_LINE_NO}{lineno}
+Sets the current line number to \var{lineno}.
+\end{funcdesc}
+
+\begin{funcdesc}{RAISE_VARARGS}{argc}
+Raises an exception. \var{argc} indicates the number of parameters
+to the raise statement, ranging from 1 to 3.  The handler will find
+the traceback as TOS2, the parameter as TOS1, and the exception
+as TOS.
+\end{funcdesc}
+
+\begin{funcdesc}{CALL_FUNCTION}{argc}
+Calls a function.  The low byte of \var{argc} indicates the number of
+positional parameters, the high byte the number of keyword parameters.
+On the stack, the opcode finds the keyword parameters first.  For each
+keyword argument, the value is on top of the key.  Below the keyword
+parameters, the positional parameters are on the stack, with the
+right-most parameter on top.  Below the parameters, the function object
+to call is on the stack.
+\end{funcdesc}
+
+\begin{funcdesc}{MAKE_FUNCTION}{argc}
+Pushes a new function object on the stack.  TOS is the code associated
+with the function.  The function object is defined to have \var{argc}
+default parameters, which are found below TOS.
+\end{funcdesc}

+\begin{funcdesc}{BUILD_SLICE}{argc}
+Pushes a slice object on the stack.  If \var{argc} is three, creates
+\code{TOS3[TOS2:TOS1:TOS]}.  Otherwise, expects three arguments.

+Prints TOS.  There is one such instruction for
+each item in the print statement.
+\end{funcdesc}

+exception has to be re-raised, or whether the function returns,
+and continues with the outer-next block.
+\end{funcdesc}

+\begin{funcdesc}{BUILD_CLASS}{}
+Creates a new class object.  TOS is the methods dictionary, TOS1
+the tuple of the names of the base classes, and TOS2 the class name.

+All of the following opcodes expect arguments.  An argument is two
+bytes, with the more significant byte last.

+\end{funcdesc}
+
+\begin{funcdesc}{IMPORT_NAME}{namei}
+Imports the module \code{co_names[namei]}.  The module object is
+pushed onto the stack.  The current name space is not affect: for a
+proper import statement, a subsequent \code{STORE_FAST} instruction
+modifies the name space.
+\end{funcdesc}
+
+\begin{funcdesc}{IMPORT_FROM}{namei}
+Imports the attribute \code{co_names[namei]}.  The module to import
+from is found in TOS and left there.

+Increments byte code counter by \var{delta}.
+\end{funcdesc}

+
+\begin{funcdesc}{RAISE_VARARGS}{argc}

+the traceback as TOS2, the parameter as TOS1, and the exception
+as TOS.
+\end{funcdesc}
+
+\begin{funcdesc}{CALL_FUNCTION}{argc}
+Calls a function.  The low byte of \var{argc} indicates the number of
+positional parameters, the high byte the number of keyword parameters.
+On the stack, the opcode finds the keyword parameters first.  For each
+keyword argument, the value is on top of the key.  Below the keyword
+parameters, the positional parameters are on the stack, with the
+right-most parameter on top.  Below the parameters, the function object
+to call is on the stack.
+\end{funcdesc}
+
+\begin{funcdesc}{MAKE_FUNCTION}{argc}

+\begin{funcdesc}{BUILD_SLICE}{argc}
+Pushes a slice object on the stack.  If \var{argc} is three, creates
