TCL Documentation?

Is the TCL language used by Draw Test Harness documented anywhere?

From Draw Test Harness I cannot even redirect the output from the "help" command to a file. That is,

help > doc.txt

displays no output but does not create the file.

I'm running version 6.6.0 in Windows 7.

Dear Michael,
Yes, TCL is used by Draw.
See for details sources of Draw package.
Best regards
