Chances are, if Alberto is not on Unix/Linux he is on Windows (assuming 
Mac OSX counts as an *ix), and TCL and TK help files are distributed 
with R.  See RHOME/Tcl/doc.  He'll still have the problem of converting 
TCL/TK documentation conventions into their R equivalents, but I think 
you've given reasonable documentation on how to do that.

I wish we had a good way to refer to these files from the rest of the 
help system.
