The plan for godoc: - Copy godoc source from the core repo to go.tools (this CL). - Break godoc into several packages inside go.tools, leaving a package main that merely sets up a local file system, interprets the command line, and otherwise delegates the heavy-lifting to the new packages. - Remove godoc from the core repo. - Update cmd/go to install this godoc binary in $GOROOT/bin. - Update misc/dist to include godoc when building binary distributions.
