copytree if directory exists

[Thomas Guettler]

Hi,

I need to copy a directory into an existing directory.
shutil.copytree does complain that the directory already
exists.

I need something like "cp -rp": Copy recursively, overwrite
if file already exist. Preserve mtime and modes if possible.

A keyword argument "may_exist= 1" for shutil.copytree would be nice.

Thomas, shutil.copytree is written in pure Python. Grab the
source and stick in the appropriate exception handling around
the call to os.mkdir() and you should have about what you
need...

Also, distutils.dir_u til has a fairly flexible copy_tree function.
