+      These are a few data structures, classes and functions which
+      we've needed over many years of Python programming and which
+      seem to be of general use to other Python programmers. Many of
+      the modules that have existed in pyutil over the years have
+      subsequently been obsoleted by new features added to the
+      Python language or its standard library, thus showing that
+      we're not alone in wanting tools like these.
