-- | Wrapper program for propellor distribution.

-- Distributions should install this program into PATH.
-- (Cabal builds it as dist/build/propellor/propellor).
--
-- This is not the propellor main program (that's config.hs).
-- This bootstraps ~/.propellor/config.hs, builds it if
-- it's not already built, and runs it.
