__doc__='''Command-line Bobo

Usage

   bobo [options] module_path [path_info]

   where:

   module_path -- is a full path to a published module

   path_info -- Is the information after the module name that would
         normally be specified in a GET URL, including a query string.

Description

   The command-line interface to Bobo provides a handy way to test,
   debug, and profile Bobo without a web server.

Options

   -u username:password        -- Supply HTTP authorization information

   -e name=value               -- Supply environment variables.  Use a
                                  seperate -e option for each variable
                                  specified.

   -p profiler_data_file       -- Run under profiler control,
                                  generating the profiler
                                  data file, profiler_data_file.

   -t                          -- Compute the time required to
                                  complete a request, in
                                  milliseconds.

   -r n                        -- Specify a repeat count for timing or
                                  profiling.

   -d                          -- Run in debug mode.  With this
                                  option, bobo will run under Python
                                  debugger control.  Two useful
                                  breakpoints are set.  The first is
                                  at the beginning of the module
                                  publishing code.  Steping through
                                  this code shows how bobo finds
                                  objects and obtains certain
                                  meta-data.  The second breakpoint is
                                  at the point just before the
                                  published object is called.  To jump
                                  to the second breakpoint, you must
                                  enter 's' followed by a carriage
                                  return to step into the module, then
                                  enter a 'c' followed by a carriage
                                  return to jump to the first
                                  breakpoint and then another 'c'
                                  followed by a carriage return to
                                  jump to the point where the object
                                  is called.  Finally, enter 's'
                                  followed a carriage return.

   -s                             Don\'t generate any output

Examples

   For example, to debug a published object (such as a method), spam,
   the following might be entered::

            bobo -d /prj/lib/python/mymod container/spam
            s
            c
            c
            s
