"""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)

1266
If to_dir exists and is a directory, the files are moved into
1267
it, keeping their old names.

Note that to_dir is only the last component of the new name;
1270
this doesn't change the directory.
1272
For each entry in from_paths the move mode will be determined
1275
The first mode moves the file in the filesystem and updates the
1276
inventory. The second mode only updates the inventory without
1277
touching the file on the filesystem. This is the new mode introduced
1280
move uses the second mode if 'after == True' and the target is not
1281
versioned but present in the working tree.
1283
move uses the second mode if 'after == False' and the source is
1284
versioned but no longer in the working tree, and the target is not
1285
versioned but present in the working tree.
1287
