[kepler-users] using string parameter in external execution actor

[Chad Berkley]

Hi Ufuk,

We haven't set a release date yet.  I'm guessing it will be later in the 
summer or in the fall, but that's just a guess.  We'll have more 
concrete dates after another project that requires Kepler is released at 
the beginning of July.
