TJC is a Tcl compiler for the TclJava project. It is written in Tcl, and produces Java as output.
From the original announcement [1 ]
Tis the season for giving and because Jacl users have been very good this year, the gift of a shiny new compiler is now available via the tcljava CVS. The compiler is named TJC, which stands for Tcl to Java Compiler. The TJC compiler accepts Tcl source code as input and compiles Tcl procs into executable Java code stored in a Jar file. The compiler is accessed via a startup script named tjc.
TJC is written by Mo DeJong with funding by AMD, New Iron Systems, and One Moon Scientific.
It is included in the TclJava 1.4.1 release, http://sourceforge.net/projects/tcljava
