Propellor's configuration file is ~/.propellor/config.hs

Let's get you started with a simple config that you can adapt
to your needs. You can start with:
   A: A clone of propellor's git repository    (most flexible)
   B: The bare minimum files to use propellor  (most simple)
Which would you prefer? [A|B] B
Initialized empty Git repository in /home/swhitton/.propellor/.git/
Creating minimal config ... done

Let's try building the propellor configuration, to make sure it will work...

Writing a default package environment file to
/home/swhitton/.propellor/cabal.sandbox.config
Creating a new sandbox at /home/swhitton/.propellor/.cabal-sandbox
Resolving dependencies...
Configuring config-0...
cabal: At least the following dependencies are missing:
propellor >=3.0
propellor: failed to make dist/setup-config

(propellor installed from Debian)
