+    "TECkit is a low-level toolkit intended to be used by other applications
+that need to perform encoding conversions (e.g., when importing legacy data
+into a Unicode-based application). The primary component of the TECkit
+package is therefore a library that performs conversions; this is the
+\"TECkit engine\". The engine relies on mapping tables in a specific binary
+format (for which documentation is available); there is a compiler that
+creates such tables from a human-readable mapping description (a simple
+text file).
+
+To facilitate the development and testing of mapping tables for TECkit,
+several applications are also included in the current package; these
+include simple tools for applying conversions to plain-text and Standard
+Format files, as well as both command-line and simple GUI versions of the
+TECkit compiler. However, it is not intended that these tools will be the
+primary means by which end users perform conversions, and they have not
+been designed, tested, and debugged to the extent that general-purpose
+applications should be.")
