The ODIE project has changed forms a few times over the years.
ODIE 1.0 still lives, I just haven't worked on it in years. It was written in those wild and wolly days when you needed to compile extensions in C for real-time apps to run properly on a 66Mhz machine.
Odie 2.0 was a pre-compiler to work around limitations in Incr Tcl.
Odie 3.0 is in active developement.
ODIE is a toolbox for assembling private collections of Tcl and C code. It uses a path in the user's home directory to compiled Tcl and Tk from scratch, as well as a bevy of binary extensions. This allows for custom binary and DLL compiles without interfering with the operating system's installed Tcl/Tk. (Or more importantly, interference FROM the operating system's installed Tcl/Tk.) Included with ODIE is the Toadkit maker. Toadkit is a zip kit to distribute self contained binaries assembled from ODIE.
Odie is destributed as a fossil repository. That repository can be accessed at: http://www.etoyoc.com:8080.
