This script is part of the omino adobe script suite.
The latest version can be found at http://omino.com/pixelblog/.

I write these because I like to. Please enjoy as you see fit.

Questions to poly@omino.com, subject line should start with
"plugins" so my spam filter lets it in.

This file has been preprocessed to be
standalone.  I develop them against some
reusable libraries -- such as for dialog
layout -- but for distribution it's nicer to
have just one file. dvb 2007.

Description: This After Effects script sets the in- our out-point of the
selected layers to the current time. It can be run as a palette, or installed
as a dockable item in ScriptUI Panels folder.
