     Package 'segmented' is aimed to estimate linear and generalized
     linear models having one or more segmented relationships in the
     linear predictor. Estimates of the slopes and of the possibly
     multiple breakpoints are provided. The package includes
     testing/estimating functions and methods to print and summarize
     the results.
