Subject mod_substitute f flag
Date Mon, 11 Feb 2008 14:46:34 GMT
The docs for mod_substitute say:

     The f flag causes mod_substitute to flatten the result of a  
substitution allowing for later substitutions to take place on the  
boundary of this one.

Can someone tell me what that means? Perhaps give an example of when  
I might want to use it? I'm unable to figure out what "flatten" means  
in this context. Is there a case when something will break if I don't  
use f?


Just because your voice reaches halfway around the world doesn't mean  
you are wiser than when it reached only to the end of the bar.
