+PyLoT: Main program
+===================
+PyLoT is a seismic data processing software capable of picking seismic
+phases (symmetric and asymmetric error assignment), exporting these to
+several common phase data formats and post process the data, e.g. locating
+events, via external localization software.
+Additionally PyLoT is meant as an interface to autoPyLoT which can
+automatically pick seismic phases, if the parameters have properly been
+chosen for the particular data set.
