+ALGLIB is a cross-platform numerical analysis and data processing
+library. ALGLIB features include:
+
+- Linear algebra (direct algorithms, EVD/SVD)
+- Solvers (linear and nonlinear)
+- Interpolation
+- Optimization
+- Fast Fourier transforms
+- Numerical integration
+- Linear and nonlinear least-squares fitting
+- Ordinary differential equations
+- Special functions
+- Statistics (descriptive statistics, hypothesis testing)
+- Data analysis (classification/regression, including neural networks)
+- Multiple precision versions of linear algebra, interpolation 
+optimization and others algorithms (using MPFR for floating point 
+computations)

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
