ArsDidita Community System (ACS) [1,2] was originally written in Tcl,
SQL and PL/SQL.  It was later rewritten in Java and XSLT with most of
the PL/SQL bits removed, and most of hand-written SQL code replaced by
an O/R mapping layer.

The original Tcl codebase was forked and continues to exist in the
form of OpenACS [3].

A fair number of client sites that we had originally developed on top
of ACS Tcl were later rewritten in other languages. (Not by us.) For
example, scorecard.org, site59.com, and developmentgateway.org all run
on something other than ACS Tcl these days.
