 Description:
 
-This mirrors the version of Freetype2 that was distributed with Ubuntu Precise
-(Version 2.4.8, git hash 9d7f0957fbd10fdbabf9815e37857a910ad4f4ac, plus
-applicable debian/patches-freetype as seen in
-https://launchpad.net/ubuntu/lucid/+source/freetype ).
-
-To get the code and patches:
-
-sudo apt-add-repository -s "deb http://archive.ubuntu.com/ubuntu precise-security main"
-sudo apt-key update
-sudo apt-get update
-apt-get source -t precise freetype=2.4.8-1ubuntu2.3
-
-and then to apply the patches (quilt):
-
-cd freetype-2.4.8/
-./debian/rules patch
-
-The tree produced by this should match the tree in this repo on the
-chromium/ubuntu/precise branch.
+This version of Freetype is updated by checking out freetype from the above git
+URL, currently it is at master@f44ddfda45eaded9, containing the latest GX
+variation font fixes.
 
 The build files should approximate the output of
 
 make -Bn | rev | cut -d ' ' -f 1 | rev | grep "\.c$" | sort
 
-Currently the cache, validators, patent checker (no longer used), and bzip2
-are excluded.
-
-We link this library into DumpRenderTree so that we can run the layout tests
-on later versions of Ubuntu and still get the same font rendering so that
-we don't have to support two sets of pixel test baselines.
+Currently the cache, patent checker (no longer used), and bzip2 are excluded.
 
 Freetype depends on two header files to be supplied by the user to specify
 how to build the library, ftconfig.h and ftmodule.h (or equivalent filenames
 as defined by the FT_CONFIG_CONFIG_H and FT_CONFIG_MODULES_H #defines).
 
-The versions in include/ were generated as follows (on a Precise machine):
+The versions in include/ were generated as follows:
 
-  % cd ext
+  % cd <dir-where-you-cloned-freetype-to>
   % bash autogen.sh
   % ./configure
   % cp objs/ftmodule.h ../include
   % cp builds/unix/ftconfig.h ../include
-  % git apply freetype2.patch
+  % git apply patches/freetype2_symbols_visbility.patch
 
-(Basically we use the stock list of modules, and define the FT_EXPORT
-and FT_EXPORT_DEF macros to work properly when building a linux shared lib.)
-
-This code is not considered security critical since it is only to be linked
-into test binaries! This should never be linked into chrome or any production
-code.
+We configure FT for using the stock list of modules, then apply the
+symbols visibility patch to define the FT_EXPORT and FT_EXPORT_DEF macros to
+work properly when building a linux shared lib.
