-The module \code{pdb} defines an interactive source code debugger for
-Python programs.  It supports setting
-(conditional) breakpoints and single stepping
-at the source line level, inspection of stack frames, source code
-listing, and evaluation of arbitrary Python code in the context of any
-stack frame.  It also supports post-mortem debugging and can be called
-under program control.

 The debugger recognizes the following commands.  Most commands can be
-abbreviated to one or two letters; e.g. ``\code{h(elp)}'' means that
-either ``\code{h}'' or ``\code{help}'' can be used to enter the help
-command (but not ``\code{he}'' or ``\code{hel}'', nor ``\code{H}'' or
-``\code{Help} or ``\code{HELP}'').  Arguments to commands must be

+\samp{Help} or \samp{HELP}).  Arguments to commands must be
 separated by whitespace (spaces or tabs).  Optional arguments are

+the last command was a \samp{list} command, the next 11 lines are
 listed.
 
 Commands that the debugger doesn't recognize are assumed to be Python
 statements and are executed in the context of the program being
 debugged.  Python statements can also be prefixed with an exclamation
-point (``\code{!}'').  This is a powerful way to inspect the program
+point (\samp{!}).  This is a powerful way to inspect the program
 being debugged; it is even possible to change a variable or call a
 function.  When an
 exception occurs in such a statement, the exception name is printed
 but the debugger's state is not changed.
 
 Multiple commands may be entered on a single line, separated by
-''\code{;;}''.  (A single ''\code{;}'' is not used as it is
+\samp{;;}.  (A single \samp{;} is not used as it is
 the separator for multiple commands in a line that is passed to
 the Python parser.)
 No intelligence is applied to separating the commands;

 The debugger supports aliases.  Aliases can have parameters which
 allows one a certain level of adaptability to the context under
 examination.

-current directory, it is read in and executed as if it had been typed
