How to use:###

• Run install.bat on windows or install.sh on linux and osx.

This creates a go directory with the golang distribution with an altered go executable.

• Copy the go directory wherever you want ($godir) and add $godir/bin to your PATH.

You can then use go without setting GOROOT, GOPATH or GOBIN.

The original go executable is replaced with a wrapper that sets those variables for the process only, and then calls the real go executable (renamed _go).

GOROOT is deduced from the location of the go executable in the PATH.

For the GOPATH, it looks for a directory called src, starting from the current directory and then looking up. If it can't find any, the current directory is used.

GOBIN is set to $GOPATH/bin.
