+%description
+    Tab is a kind of general-purpose query language for text files.
+    Tab is a special programming language unlike any other: it's
+    statically-typed and type-infered; it also infers memory consumption
+    and guarantees O(n) memory use; it is designed for concise
+    one-liner computations right in the shell prompt; it features both
+    a mathematics library and a set of data slicing and aggregation
+    primitives; it is faster than all other interpreted languages with a
+    similar scope; it is not Turing-complete (But can compute virtually
+    anything nonetheless); it is self-contained: distributed as a single
+    statically linked binary and nothing else; and it has no platform
+    dependencies.
