Hello,
As far as I can see, fpm can read in from a ".fpm" file in the local directory for getting it's command line arguments. Is there a way to specify an arbiraty confile file rather than just the ".fpm" file? - I'd like to be able to maintain lots of similar config files in the same place. e.g. I could call fpm with

fpm --config package1.fpm
fpm --config package2.fpm 

where package1.config and package2.config are distinct ".fpm" files. This would help make things easier to automate for building many packages.
Thank you!
