Using automake to check for cups version, etc

[Josh Mathis]

I would like to use automake, etc. in my filter distribution. What would 
be the preferred (most portable) way of checking for a specific CUPS 
version (I am requiring >=1.2), verifying that CUPS dev libraries are 
installed, and obtaining my ppd and filter paths? Would any of the 
config scripts included with the CUPS source be suitable for including 
in my acinclude?

Thanks
Josh
