 hg update weekly.<i>YYYY-MM-DD</i>

+<h2 id="2011-12-22">2011-12-22</h2>
+
+<pre>
+This snapshot includes changes to the images/ycbcr and testing packages, and
+changes to the build system.
+
+The types for managing Y'CbCr images in the image/ycbcr have been moved to the
+image and image/color packages. A gofix module will rewrite affected code.
+
+The testing package's B type (used when running benchmarks) now has the same
+methods as T (used in tests), such as Print, Error, and Fatal.
+
+This weekly adds a new command named 'go' for building and testing go programs.
+For Go 1, the go command will replace the makefile-based approach that we have
+been using. It is not yet ready for general use, but all.bash does use it to
+build the tree. If you have problems building the weekly, you can 'export
+USE_GO_TOOL=false' before running all.bash to fall back to the makefiles.
+

+* archive/zip: add SetModTime method to FileHeader.
+* build: make use of env (thanks Mikio Hara),
