# 11.11 `distutils.dir_util` -- Directory tree operations

This module provides functions for operating on directories and trees of directories.

`mkpath`( | name[, mode=`0777`, verbose=`0`, dry_run=`0`])

  Create a directory and any missing ancestor directories. If the directory already exists (or if name is the empty string, which means the current directory, which of course exists), then do nothing. Raise `DistutilsFileError` if unable to create some directory along the way (eg. some sub-path exists, but is a file rather than a directory). If verbose is true, print a one-line summary of each mkdir to stdout. Return the list of directories actually created.

`create_tree`( | base_dir, files[, mode=`0777`, verbose=`0`, dry_run=`0`])

  Create all the empty directories under base_dir needed to put files there. base_dir is just the a name of a directory which doesn't necessarily exist yet; files is a list of filenames to be interpreted relative to base_dir. base_dir + the directory portion of every file in files will be created if it doesn't already exist. mode, verbose and dry_run flags are as for `mkpath()`.

`copy_tree`( | src, dst[preserve_mode=`1`, preserve_times=`1`, preserve_symlinks=`0`, update=`0`, verbose=`0`, dry_run=`0`])

  Copy an entire directory tree src to a new location dst. Both src and dst must be directory names. If src is not a directory, raise `DistutilsFileError`. If dst does not exist, it is created with `mkpath()`. The end result of the copy is that every file in src is copied to dst, and directories under src are recursively copied to dst. Return the list of files that were copied or might have been copied, using their output name. The return value is unaffected by update or dry_run: it is simply the list of all files under src, with the names changed to be under dst.

  preserve_mode and preserve_times are the same as for `copy_file` in `distutils.file_util`; note that they only apply to regular files, not to directories. If preserve_symlinks is true, symlinks will be copied as symlinks (on platforms that support them!); otherwise (the default), the destination of the symlink will be copied. update and verbose are the same as for `copy_file()`.

`remove_tree`( | directory[verbose=`0`, dry_run=`0`])

  Recursively remove directory and all files and directories underneath it. Any errors are ignored (apart from being reported to `sys.stdout` if verbose is true).

Some of this could be replaced with the shutil module?
