How to tell which version of Rev created a stack

[Marian Petrides]

Hi, all,

I have an application I created years ago in an early version of Rev   
(somewhere between 2.1.2 and 2.5) in which I am trying to update the  
content. Since I have found the app as written works fine on all  
platforms I am interested in, including Vista,  I see no reason to  
update it to a newer version of Rev before I do the content update.

The problem is I can't remember which version of Rev I originally  
used to develop the app.  Is there some way to determine which  
version of Rev was used to develop a particular app?

Thanks.

Marian
