[mod] Tools to install and maintain golang [1] binaries & packages. 

[1] https://golang.org/doc/devel/release#policy



A simple *helloworld* test with user 'my_user' :

  sudo -H adduser my_user
  ./manage go.golang go1.17.3 my_user
  ./manage go.install github.com/go-training/helloworld@latest my_user
  ./manage go.bash my_user
  $ helloword
  Hello World!!

Don't forget to remove 'my_user':  sudo -H deluser --remove-home my_user
