ptemcee
=======

**ptemcee** /'tɛmsiː/ (noun):
    `Adaptive parallel tempering <http://arxiv.org/abs/1501.05823>`_ meets |emcee|_.

*ptemcee*, pronounced "tem-cee", is fork of Daniel Foreman-Mackey's |emcee|_ to implement parallel
tempering more robustly.  As far as possible, it is designed as a drop-in replacement for *emcee*.

If you're trying to characterise awkward, multi-modal probability distributions, then *ptemcee* is
your friend.
