+class Stats:
+    """This class is used for creating reports from data generated by the
+    Profile class.  It is a "friend" of that class, and imports data either
+    by direct access to members of Profile class, or by reading in a dictionary
+    that was emitted (via marshal) from the Profile class.
+
+    The big change from the previous Profiler (in terms of raw functionality)
+    is that an "add()" method has been provided to combine Stats from
+    several distinct profile runs.  Both the constructor and the add()
+    method now take arbitrarily many file names as arguments.
+
+    All the print methods now take an argument that indicates how many lines
+    to print.  If the arg is a floating point number between 0 and 1.0, then
+    it is taken as a decimal percentage of the available lines to be printed
+    (e.g., .1 means print 10% of all available lines).  If it is an integer,
+    it is taken to mean the number of lines of data that you wish to have
+    printed.
+
+    The sort_stats() method now processes some additional options (i.e., in
+    addition to the old -1, 0, 1, or 2).  It takes an arbitrary number of
+    quoted strings to select the sort order.  For example sort_stats('time',
+    'name') sorts on the major key of 'internal function time', and on the
+    minor key of 'the name of the function'.  Look at the two tables in
+    sort_stats() and get_sort_arg_defs(self) for more examples.
+
+    All methods return self,  so you can string together commands like:
+        Stats('foo', 'goo').strip_dirs().sort_stats('calls').\
