+those it provides a framework and a Tcl/Tk enabled GUI for optimizing baseline
+algorithm parameters.  Typical use is the removal of the background effects from
+spectra, which are originating from various types of spectroscopy and spectrometry.
+Also, there is a possibility of optimizing this with regard to regression or
+classification results.  Correction methods include polynomial fitting, weighted
+local smoothers and many more.")
