    The Beyond and below are like a deep of ocean, and we the creatures
    that swim in the abyss.  We're so far down that the beings on the
    surface -- superior though they are -- can't effectively reach us.
    Oh, they fish, and they sometimes blight the upper levels with
    points we don't even understand.  But the abyss remains a relatively
    safe place.

    -- Vernor Vinge, A Fire Upon the Deep

On behalf of the Parrot team, I'm proud to announce Parrot 2.0.0
"Inevitable." Parrot (http://parrot.org/) is a virtual machine aimed
at running all dynamic languages.

Parrot 2.0.0 is available on Parrot's FTP site, or follow the download
instructions at http://parrot.org/download.  For those who would like to

Subversion
