Version 1.1

An InDesign CS5 Javascript
Bruno Herfst 2015

Move text to an inline frame for further manipulation.
Rotate for example.

NOTE: This script uses the bounds to set the size and therefore does not work inside
      text frames that already have been rotated.
      It does not work with obkect srtyles in folers
