Global Options

These options may be used with any command, and may appear in front of any
command.  (e.g. "bzr --profile help").

--version      Print the version number. Must be supplied before the command.
--no-aliases   Do not process command aliases when running this command.
--builtin      Use the built-in version of a command, not the plugin version.
               This does not suppress other plugin effects.
--no-plugins   Do not process any plugins.

--profile      Profile execution using the hotshot profiler.
--lsprof       Profile execution using the lsprof profiler.
--lsprof-file  Profile execution using the lsprof profiler, and write the
               results to a specified file.  If the filename ends with ".txt",
               text format will be used.  If the filename either starts with
               "callgrind.out" or end with ".callgrind", the output will be
               formatted for use with KCacheGrind. Otherwise, the output
               will be a pickle.

See doc/developers/profiling.txt for more information on profiling.
A number of debug flags are also available to assist troubleshooting and
development.

-Dauth         Trace authentication sections used.
-Derror        Instead of normal error handling, always print a traceback on

               operations.
-Dhashcache    Log every time a working file is read to determine its hash.
-Dhooks        Trace hook execution.
-Dhttp         Trace http connections, requests and responses
-Dhpss         Trace smart protocol requests and responses.
-Dindex        Trace major index operations.
-Dlock         Trace when lockdir locks are taken or released.
