[ale] here's one for the script wizards

[Asher Vilensky]

Sorry, I wasn't specific enough.  I'm looking to separate all the
parenthesized words from the non-parenthesized:

input: foo (bar) ice cream (brown) sky is blue (airplane flies) just flies

output:
foo ice cream sky is blue just flies
(bar) (brown) (airplane flies)     --- with or without parenthesis, it
doesn't matter.
