"""WorkingTree object and friends.
19
A WorkingTree represents the editable working copy of a branch.
20
Operations which represent the WorkingTree are also done here,
21
such as renaming or adding files. The WorkingTree has an inventory
22
which is updated by these operations. A commit produces a
23
new revision based on the workingtree and its inventory.
25
At the moment every WorkingTree has its own branch. Remote
26
WorkingTrees aren't supported.
28
To get a WorkingTree, call bzrdir.open_workingtree() or
29
WorkingTree.open(dir).

38
# copy, and making sure there's only one WorkingTree for any directory on disk.
39
# At the moment they may alias the inventory and have old copies of it in

Formats provide three things:
1428
* An initialization routine,

Formats are placed in an dict by their format string for reference
1433
during workingtree opening. Its not required that these be instances, they

can be classes themselves with class methods - it simply depends on
1435
whether state is needed for a given format or not.

methods on the format class. Do not deprecate the object, as the

object will be created every time regardless.
