Add freetxl, a unique programming language specifically designed to support

computer software analysis and source transformation tasks. It is the
evolving result of more than fifteen years of concentrated research on
rule-based structural transformation as a paradigm for the rapid solution
of complex computing problems.

+TXL is a unique programming language specifically designed to support computer
+software analysis and source transformation tasks. It is the evolving result
+of more than fifteen years of concentrated research on rule-based structural
+transformation as a paradigm for the rapid solution of complex computing
+problems.
+
+The TXL programming language is a hybrid functional / rule-based language with
+unification, implied iteration and deep pattern match.
+
+Each TXL program has two components:
+
+ * A Description of the Structures to be Transformed
+   Specified as an EBNF grammar, in context-free ambiguous form.
+ 
+ * A Set of Structural Transformation Rules
+   Specified by example, using pattern/replacement pairs.
