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.
