+Tash (previously known as Tcl Ada Shell) is an Ada binding to Tcl/Tk.
+
+Its purpose is to
+
+* allow a Tcl program to use Ada in place of C to implement Tcl
+  commands where additional execution speed, more complex data
+  structures, or better name space management is needed, and
+
+* support the rapid development of Platform-Independent Graphical User
+  Interfaces via Tk.
+
+Please note that, on macOS, tash assumes that Tcl/Tk is provided via
+[Homebrew](https://brew.sh).
