+Description: Researchers working with Qualitative Comparative Analysis (QCA)
+    can use the package to estimate power of a sufficient term
     using permutation tests. A term can be anything: A condition, conjunction or 
     disjunction of any combination of these. The package further allows users to plot 
     the estimation results and to estimate the number of cases required to achieve a
     certain level of power, given a prespecified null and alternative hypothesis.
