+    matplotlib now requires python2.4, so matplotlib.cbook will no
+    loner provide set, enumerate, reversed or izip compatability functions
+
     In numpy 1.0 bins are specified by the left edges only.  The axes
     method "hist" now uses future numpy 1.3 semantic for histograms. 
     Providing binedges, the last value gives the upper-right edge now,

+2008-05-16 removed some unneeded code w/ the python 2.4 requirement.
+           cbook no longer provides compatibility for reversed,
+           enumerate, set or izip.  removed lib/subprocess, mpl1,
+           sandbox/units, and the swig code.  This stuff should remain
+           on the maintenance branch for archival purposes. JDH
