 Name: freetype2
 URL: git://git.sv.nongnu.org/freetype/freetype2.git
-Version: 2.3.11
+Version: 2.4.8-1ubuntu2.1
 Security Critical: no
 License: BSD
 License File: NOT_SHIPPED
 
 Description:
 
-This mirrors the version of Freetype2 that was distributed with Ubuntu Lucid
-(Version 2.3.11, git hash d699c2994ecc178c4ed05ac2086061b2034c2178, as seen
-in https://launchpad.net/ubuntu/lucid/+source/freetype ).
+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 ). On Ubuntu Precise
+this code should be the same as the result of
+
+apt-get source freetype && cd freetype-2.4.8/ && ./debian/rules patch
+
+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.
