+in Wolpert (2015), ACME: A Partially Periodic Estimator of Avian & Chiropteran
+Mortality at Wind Turbines.  Unlike most other models, this estimator supports
+decreasing-hazard Weibull model for persistence; decreasing search proficiency
+as carcasses age; variable bleed-through at successive searches; and interval
+mortality estimates.  The package provides, based on search data, functions
+for estimating the mortality inflation factor in Frequentist and Bayesian
+settings.")
