            PYMASK: Python aperture masking analysis pipeline
--------------------------------------------------------------------
---
pymask is a python module for fitting models to aperture masking
data reduced to oifits format by the IDL masking pipeline.

It consists of a class, cpo, which stores all the relevant information
from the oifits file, and a set of functions, cp_tools, for manipulating
these data and fitting models.

Fitting is based on the MCMC Hammer algorithm (aka ensemble affine
invariant MCMC) or the MultiNest algorithm (aka multimodal nested
sampling). Both of these must be installed correctly or else
pymask won't work!
See readme.txt for more details.
