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.)
