vcd file generator for signal dump in tcl

I have an application mostly written in tcl for silicon validation.
One thing I want to do is capture some signals and pass them on to the
verification folks to check. They prefer the signal capture data to be
in VCD format so that they can view the results with their favorite
signal viewer tools (e.g., signalscan, etc). So, I need to convert the
captured trace from my tool to VCD.

Does anyone have some code that they wouldn't mind passing on or
pointing me to that writes out a file to VCD. If you had code in TCL,
that would be outstanding, but even code in perl, python, etc would be
useful.

Thanks a lot in advance!

....probably overkill for what you need, but there's working code.
