[Click] possible to use variables in config file?

[Marcel Poisot]

I was hoping to clean up my Click config file a little bit, by putting 
declarations of variables (such as dump pathnames, net dev names, etc) 
at the top of the file.

Is there anyway to just make a variable name?  I have some absolute path 
names for dumps, and it would be nice to keep the base of the path in 
some variable name for easier maintenance.  Is there a way to do this? 
The same applies for frequently used parameters and the like.

BTW, I noticed AddessInfo and PortInfo aren't linked anywhere in the 
element documentation pages.  I just guessed their URLs...


Also, is there a way to instantiate or use a Click element from WITHIN a 
click element?  It would be nice to internally call FixTCPChecksum from 
within the element I'm creating, as opposed to doing it myself or 
requiring the user to string that element after mine with every use.
