Set up the checkout for Go development.
usage: fx setup-go [-d] Creates symlinks from //third_party/golibs into the root of the tree and the //vendor directory so that standard Go tooling and IDE features will work. All of the symlink paths should already be ignored by git, so this symlinking will not require any .gitignore modifications. This is not necessary for development, only to improve the experience when using Go IDE features and standard tooling. Prints the names of any symlinks it creates or removes, unless the operation is a no-op, in which case it prints nothing. optional arguments: -d Tear down the symlinks created by `fx setup-go`. Also idempotent (i.e. safe to run multiple times in a row).
