   There are two kinds of matplotlib backends: vector based and raster
-  based.  The vector based backends, SVG and PS, produce ASCII text
-  output files *.svg and *.ps.  The core raster based renderer is the
-  http://antigrain.com (agg) backend.  This is a high quality 2D

-  The top of setup.py contains some flags controlling which backends
-  will be built.  If you want to use a GUI backend, you will need
-  either Tkinter, pygtk or wxpython installed on your system, from src
-  or from a package manager including the devel packages.  You can
-  choose which backends to enable by setting the flags in setup.py,
-  but the 'auto' flags will work in most cases, as matplotlib tries to
-  find a GUI and build the backend acccordingly.  If you know you
-  don't want a particular backend or extension, you can set that flag
-  to False.
+  matplotlib ships with a setup.cfg.template which you can use to
+  customize the build process.  Copy it to setup.cfg if you need to
+  customize something.  See that files for details of the parameters
+  you can set.
 
-  As discussed above, most users will want to set 'BUILD_AGG = 1' and
-  one or more of the GUI backends to True.  Exceptions to this are if
-  you know you don't need a GUI (eg a web server) or you only want to
-  produce vector graphics.

+  is to automatically detect your installed GUIs and build support for
+  them.  If you later find that you did not have a GUI toolkit like
+  pygtk installed when you built matplotlib, but now want it, you will
+  need to install the toolkit and rebuild matplotlib.
