<p>The <a class="reference internal" href="#module-shutil" title="shutil: High-level file operations, including copying."><tt class="xref py py-mod docutils literal"><span class="pre">shutil</span></tt></a> module offers a number of high-level operations on files and
collections of files.  In particular, functions are provided  which support file
copying and removal. For operations on individual files, see also the
<a class="reference internal" href="os.html#module-os" title="os: Miscellaneous operating system interfaces."><tt class="xref py py-mod docutils literal"><span class="pre">os</span></tt></a> module.</p>

<p class="last">On POSIX platforms, this means that file owner and group are lost as well
as ACLs.  On Mac OS, the resource fork and other metadata are not used.
This means that resources will be lost and file type and creator codes will
not be correct. On Windows, file owners, ACLs and alternate data streams
are not copied.</p>

<p><em>base_name</em> is the name of the file to create, including the path, minus

archive.</p>
<p><em>base_dir</em> is the directory where we start archiving from;
ie. <em>base_dir</em> will be the common prefix of all files and
directories in the archive.</p>
<p><em>root_dir</em> and <em>base_dir</em> both default to the current directory.</p>
<p><em>owner</em> and <em>group</em> are used when creating a tar archive. By default,
uses the current owner and group.</p>
