> There have been some requests on the Porter discussion list for ConfigurationFile to support arithmetic operations.  A use case for this feature is to facilitate configuring services with a set of consecutive ports open in a firewall.
> Below is the use case provided by Van Simmons from Invesco:
> "...my particular case was in wanting to use a range of port numbers for my various services so that I could open some holes in a firewall and allow access to the services.  In that case, I would like to pass in ${basePortNumber} as variable, have reggie use ${basePortNumber}, outrigger use ${basePortNumber}+1, et al.  That way, if I decided to move things around I could do that without revisiting all my config files."
> While ${basePortNumber} could not be used directly in an addition expression because it is of type String, it would be possible to do something like Integer.parseInt(${basePortNumber}) + 1.
