+This weekly snapshot includes a re-organization of the Go tools.
+
+Only the go, godoc, and gofmt tools are installed to $GOROOT/bin (or $GOBIN).
+The remainder are installed to $GOROOT/bin/tool.
+This puts the lesser-used tools (6g, cgo, govet, etc.) outside the user PATH.
+Instead these tools may be called through the go tool with 'go tool command'.
+For example, to vet hello.go you would type 'go tool vet hello.go'.
+Type 'go tool' see the list of available tools.
+
+With the move, some tools were given simpler names:
+	6cov    -&gt; cov
+	6nm     -&gt; nm
+	goapi   -&gt; api
+	gofix   -&gt; fix
+	gopack  -&gt; pack
+	gopprof -&gt; pprof
+	govet   -&gt; vet
+	goyacc  -&gt; yacc
+
+The os/signal package has been moved to exp/signal.
+
+A new tool named 'dist' has been introduced to handle building the gc tool
+chain and to bootstrap the go tool. The old build scripts and make files
+have been removed.
