factor out environment variable checks.
infer $GOROOT etc during build if not set.
it's still necessary to set them for yourself
to use the standard Makefiles.

when running all.bash, don't recompile all the
go packages in run.bash, since make.bash already did.

Add a custom mapper for Turkish and Azeri.

A more general solution for deriving the case information from Unicode's
SpecialCasing.txt will require more work.

instead use pure substring matching to find template values.

this makes stdZulu unnecessary and allows formats
like "20060102 030405" (used in some internet protocols).

this makes Parse not handle years < 0000 or > 9999 anymore.
that seems like an okay price to pay, trading hypothetical
functionality for real functionality.

also changed the comments on the Time struct to use the
same reference date as the format and parse routines.

the set() method and add() functions.  But we rename add() to Var() for consistency.
Also rename FlagValue to Value for simplicity.

Also, delete the check for multiple settings for a flag.  This makes it possible to
define a flag that collects values, such as into a slice of strings.

type flagVar []string

func (f *flagVar) String() string {
	return fmt.Sprint(v)
}

func (f *flagVar) Set(value string) bool {
	if v == nil {
		v = make(flagVar, 1)
	} else {
		nv := make(flagVar, len(v)+1)
		copy(nv, v)
		v = nv
	}
	v[len(v)-1] = value
	return true
}

var v flagVar

func main() {
	flag.Var(&v, "testV", "multiple values build []string")
	flag.Parse()
	fmt.Printf("v = %v\n", v)
