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.

there.
'base_dir' is just the 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()'.

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'; 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'.
