Bring changes from the repository into the working copy.
usage: update [PATH...]
If no revision is given, bring working copy up-to-date with HEAD rev.
Else synchronize working copy to revision given by -r.
For each updated item a line will start with a character reporting the
action taken. These characters have the following meaning:
A Added
D Deleted
U Updated
C Conflict
G Merged
E Existed
A character in the first column signifies an update to the actual file,
while updates to the file's properties are shown in the second column.
A 'B' in the third column signifies that the lock for the file has
been broken or stolen.
If --force is used, unversioned obstructing paths in the working
copy do not automatically cause a failure if the update attempts to
add the same path. If the obstructing path is the same type (file
or directory) as the corresponding path in the repository it becomes
versioned but its contents are left 'as-is' in the working copy.
This means that an obstructing directory's unversioned children may
also obstruct and become versioned. For files, any content differences
between the obstruction and the repository are treated like a local
modification to the working copy. All properties from the repository
are applied to the obstructing path. Obstructing paths are reported
in the first column with code 'E'.
Use the --set-depth option to set a new working copy depth on the
targets of this operation. Currently, the depth of a working copy
directory can only be increased (telescoped more deeply); you cannot
make a directory more shallow.
