<p>On non-Windows OSes, <tt class="docutils literal"><span class="pre"><span class="Identifier">options</span></span></tt> specify the way file is copied; by default, if <tt class="docutils literal"><span class="pre"><span class="Identifier">source</span></span></tt> is a symlink, copies the file symlink points to. <tt class="docutils literal"><span class="pre"><span class="Identifier">options</span></span></tt> is ignored on Windows: symlinks are skipped.</p>

<p>If <tt class="docutils literal"><span class="pre"><span class="Identifier">dest</span></span></tt> already exists, the file attributes will be preserved and the content overwritten.</p>
<p>On OSX, <tt class="docutils literal"><span class="pre"><span class="Identifier">copyfile</span></span></tt> C api will be used (available since OSX 10.5) unless <tt class="docutils literal"><span class="pre"><span class="Operator">-</span><span class="Identifier">d</span><span class="Punctuation">:</span><span class="Identifier">nimLegacyCopyFile</span></span></tt> is used.</p>
