+      eplot ("easy gnuplot") is a ruby script which allows to pipe data easily
+      through gnuplot and create plots quickly, which can be saved in
+      postscript, PDF, PNG or EMF files. Plotting of multiple files into a
+      single diagram is supported.
+
+      This package also includes the complementary 'ec' tool (say "extract
+      column").
