+		Wolfram Mathematica is a software system with built-in libraries for
+		several areas of technical computing that allow machine learning,
+		statistics, symbolic computation, data manipulation, network analysis,
+		time series analysis, plotting functions and various types of data,
+		implementation of algorithms, creation of user interfaces, and interfacing
+		with programs written in other programming languages.
