566.7.1 The <tt class="class">dircmp</tt> class
57</H2>
58
59<P>
60<tt class="class">dircmp</tt> instances are built using this constructor:

66<dd>
67Construct a new directory comparison object, to compare the
68directories <var>a</var> and <var>b</var>. <var>ignore</var> is a list of names to
69ignore, and defaults to <code>['RCS', 'CVS', 'tags']</code>. <var>hide</var> is a
70list of names to hide, and defaults to <code>[os.curdir, os.pardir]</code>.
71</dl>
72
73<P>
74The <tt class="class">dircmp</tt> class provides the following methods:

99subdirectories (recursively).

101
102<P>
103The <tt class="class">dircmp</tt> offers a number of interesting attributes that may
104be used to get various bits of information about the directory trees
105being compared.
106
107<P>
108Note that via <tt class="method">__getattr__()</tt> hooks, all attributes are
109computed lazily, so there is no speed penalty if only those
110attributes which are lightweight to compute are used.
