emcee is a stable, well tested Python implementation of the affine-invariant \
ensemble sampler for Markov chain Monte Carlo (MCMC) proposed by             \
Goodman & Weare (2010). The code is open source and has already been         \
used in several published projects in the Astrophysics literature.
