+title: 'CroptimizR: A Package to Estimate Parameters of Crop Models'
+version: 0.5.1
+abstract: The purpose of CroptimizR is to provide functions for estimating crop model
+  parameters from observations of their simulated variables. This process is often
+  referred to as calibration. For that, it offers a generic framework for linking
+  crop models with up-to-date and ad-hoc algorithms, as well as a choice of goodness-of-fit
+  criteria and additional features adapted to the problem of crop model calibration.
+  It facilitates the comparison of different types of methods on different models.
