+2007-08-06 Removed mathtext2
+
+2007-07-31 Refactoring of distutils scripts.
+ - Will not fail on the entire build if an optional Python
+ package (e.g. Tkinter) is installed but its development
+ headers are not (e.g. tk-devel). Instead, it will
+ continue to build all other extensions.
+ - Provide an overview at the top of the output to display
+ what dependencies and their versions were found, and (by
+ extension) what will be built.
+ - Use pkg-config, when available, to find freetype2, since
+ this was broken on Mac OS-X when using MacPorts in a non-
+ standard location.
+
2007-07-30 Reorganized configuration code to work with traited config
objects. The new config system is located in the
matplotlib.config package, but it is disabled by default.

-
-In order to use mathtext2, you must build matplotlib.ft2font. This is
-built by default in the windows installer.
-
-For other platforms, edit setup.py and set
-
-BUILD_FT2FONT = True
-
-You have to put the following lines in your matplotlibrc file if you want to
-enable mathtext2 globaly (not needed for running this example):
-
-mathtext.mathtext2: True # Needed to enable the new mathtext
-mathtext.rm : FreeSerif.ttf
-mathtext.it : FreeSerifItalic.ttf # Text italic
-mathtext.tt : FreeMono.ttf # Typewriter (monospaced)
-mathtext.mit : FreeSerifItalic.ttf # Math italic
-mathtext.cal : FreeSansOblique.ttf # Caligraphic
-mathtext.nonascii: FreeSerif.ttf # #Used for \sum, \infty etc.
-
-Note that "FreeSerif.ttf" etc. may be replaced by any font. Font files must be
-in your system's font path.
-
-Only the first parameter must be set (mathtext2 uses BaKoMa fonts by
-default, and they come packaged with matplotlib, so the above lines
-override them) because mathtext2 is disabled by default.
-
-This demo assumes that you have FreeSerif.ttf installed.
-You can get FreeSerif.ttf (and other files) from:
-http://download.savannah.gnu.org/releases/freefont/
-if you are on windows. On linux, they are usually shipped by default.
-FreeFonts are distributed under GPL.
