Hi all,  
I want to ask about ideas of rails app versioning. I got app in  
development and want to know version that client is running. I can  
write some version string in application.html to show version…  
Other idea is to find the newest file (its date) in rails app  
directory - it can mark the “last change” of app - can someone give me  
clues how to do this (find newest filedate in dir incrementally) in  
rails?  
Any other ideas of app versioning? I know that it would be good to  
include revision number from repo like svn…  
BR

You could use an SVN keyword to insert the current revision in a file.

Put ‘$Revision$’ in one of your files, then:  
$ svn propset svn:keywords Revision   
to enable expansion of the keyword in your file.

Then, by looking in this file, you can determine which revision is in  
use.
