Commands are the heart of the command-line bzr interface.
150
151
The command object mostly handles the mapping of command-line
152
parameters into one or more bzrlib operations, and of the results
153
into textual output.
154
155
Commands normally don't have any state. All their arguments are
156
passed in to the run method. (Subclasses may take a different
157
policy if the behaviour of the instance needs to depend on e.g. a
158
shell plugin and not just its Python class.)

160

The docstring for an actual command should give a single-line

summary, then a complete description of the command. A grammar

179
81
takes_options
180
List of options that may be given for this command. These can
181
be either strings, referring to globally-defined options,
182
or option objects. Retrieve through options().
82
List of options that may be given for this command.
