comprises two languages integrated into a single tool: a text scanning and
extraction language referred to as the TXR Pattern Language (sometimes just
\"TXR\"), and a general-purpose dialect of Lisp called TXR Lisp.  TXR can be
used for everything from \"one liner\" data transformation tasks at the
command line, to data scanning and extracting scripts, to full application
development in a wide-range of areas.")
