"""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).
32
# TODO: Give the workingtree sole responsibility for the working inventory;
33
# remove the variable and references to it from the branch. This may require
34
# updating the commit code so as to update the inventory within the working
35
# copy, and making sure there's only one WorkingTree for any directory on disk.
36
# At the moment they may alias the inventory and have old copies of it in
37
# memory. (Now done? -- mbp 20060309)
