Many commands apply to a set of packages:

	go <action> [packages]

Usually, [packages] is a list of import paths.

An import path that is a rooted path or that begins with
a . or .. element is interpreted as a file system path and
denotes the package in that directory.

	// i.e., locally vendored packages may not be found.
	// The types package does not call Import if an ImporterFrom
	// is present.
	Importer

	// ImportFrom returns the imported package for the given import
	// path when imported by a package file located in dir.
	// If the import failed, besides returning an error, ImportFrom
	// is encouraged to cache and return a package anyway, if one

//
// The //go:embed directive can be used with both exported and unexported variables,
// depending on whether the package wants to make the data available to other packages.
// It can only be used with variables at package scope, not with local variables.
//
// Patterns must not match files outside the package's module, such as ‘.git/*’ or symbolic links.

		// imports. TestStdlib will collect errors once for each package.
		return pkg, nil
	}
	return nil, err
}

// getDirPackage gets the package defined in dir from the future cache.
//
// If this is the first goroutine requesting the package, getDirPackage
// type-checks.
func (c *stdlibChecker) getDirPackage(dir string) (*Package, error) {
	c.mu.Lock()
	fut, ok := c.pkgs[dir]
	if !ok {

// Existing packages should not have their constraints relaxed
// without prior discussion.
// Negative assertions should almost never be removed.
//
// "a < b" means package b can import package a.
//
// See `go doc internal/dag' for the full syntax.
//
// All-caps names are pseudo-names for specific points
// in the dependency lattice.

	UsageLine: "go clean [clean flags] [build flags] [packages]",
	Short:     "remove object files and cached files",
	Long: `
Clean removes object files from package source directories.
The go command builds most objects in a temporary directory,
so go clean is mainly concerned with object files left by other
tools or by manual invocations of go build.

If a package argument is given or the -i or -r flag is set,

			a.Target = "DO NOT USE - " + a.Mode
			return true
		}
		// Special case for building a main package: if the only thing we
		// want the package for is to link a binary, and the binary is
		// already up-to-date, then to avoid a rebuild, report the package
		// as up-to-date as well. See "Build IDs" comment above.
		// TODO(rsc): Rewrite this code to use a TryCache func on the link action.
