 Glymur 0.6 works on Python versions 2.7, 3.3 and 3.4.  If you have Python 2.6,
 you should use the 0.5 series of Glymur.
 
-OpenJPEG Installation
-=====================
-Glymur will read JPEG 2000 images with versions 1.3, 1.4, 1.5, 2.0,
-and the trunk/development version of OpenJPEG.  Writing images is
-only supported with the 1.5 or better, however, and the trunk/development
-version of OpenJPEG is strongly recommended.  For more information about
-OpenJPEG, please consult http://www.openjpeg.org.
-
-If you use MacPorts or if you have a sufficiently recent version of
-Linux, your package manager should already provide you with a version of
-OpenJPEG 1.X which glymur can already use.  
+For more information about OpenJPEG, please consult http://www.openjpeg.org.
