Humanizing sqlplus

It's always been frustrating to me that sqlplus does not have REPL behavior, so you can't arrow-up through your history, etc. In addition, the default SQL prompt is not very informative. Since I often work on prod and dev databases at the same time, it is important to me that I know where I am when I am executing disastrous SQL.

Well, rlwrap to the rescue! Plus, a handy login.sql script to customize your sqlplus prompt. The package was available by default in RHEL6 and on OSX El Capitan. YMMV...
