description \
    R is GNU S - an interpreted language for statistical computing

long_description \
    R is a language and environment for statistical computing and graphics. \
    R provides a wide variety of statistical (linear and nonlinear modeling, \
    classical statistical tests, time-series analysis, classification, \
    clustering, ...) and graphical techniques, and is highly extensible.
