Quick answer: I want to have my Grails app determine at runtime which
version it was deployed as (bad English, I know).

Longer answer:

I want to use parallel deployment as an easy way to allow existing
sessions to continue while redirecting new sessions to a "down for
temp maintenance page."

My thought was to

1) Have app check context version before each controller action.  If
version is '~~~' (late in sorting order), redirect user to maintenance
page.

2) Deploy app with version '~~~'.  Normal condition, app is stopped.

Now all I have to do is start this context whenever I want to
accomplish temp outage.
