 \description{
 This package brings into R the hydrological modelling tools developed at INRAE-Antony (formerly IRSTEA, HYCAR Research Unit, France), including rainfall-runoff models (\strong{GR4H}, \strong{GR5H}, \strong{GR4J}, \strong{GR5J}, \strong{GR6J}, \strong{GR2M}, \strong{GR1A}) and a snow accumulation and melt model (\strong{CemaNeige}). Each model core is coded in Fortran to ensure low computational time. The other package functions (i.e. mainly the calibration algorithm and the computation of the efficiency criteria) are coded in R. \cr\cr
 
 
 ## --- Functions and objects
 
-The airGR package has been designed to fulfil two major requirements: facilitate the use by non-expert users and allow flexibility regarding the addition of external criteria, models or calibration algorithms. The names of the functions and their arguments were chosen to this end.

 The package is mostly based on three families of functions:
