+    (description
+     "Tabular provides a Haskell representation of two-dimensional data
+tables, the kind that you might find in a spreadsheet or or a research report.
+It also comes with some default rendering functions for turning those tables
+into ASCII art, simple text with an arbitrary delimiter, CSV, HTML or LaTeX.
+
+Below is an example of the kind of output this library produces.  The tabular
+package can group rows and columns, each group having one of three
+separators (no line, single line, double line) between its members.
+
+@example
+
+    || memtest 1 | memtest 2 ||  time test  | time test 2
+====++===========+===========++=============+============
+A 1 ||       hog |  terrible ||        slow |      slower
+A 2 ||       pig |   not bad ||        fast |     slowest
+----++-----------+-----------++-------------+------------
+B 1 ||      good |     awful || intolerable |    bearable
+B 2 ||    better | no chance ||    crawling |     amazing
+B 3 ||       meh |   well... ||  worst ever |          ok
