## NOTES FOR STAYING IN PRIMARY INTERPRETER:
##
## If you set ::tkcon::OPT(exec) to {}, then instead of a multiple
## interp model, you get tkcon operating in the main interp by default.
## This can be useful when attaching to programs that like to operate
## in the main interpter (for example, based on special wish'es).
## You can set this from the command line with -exec ""
## A side effect is that all tkcon command line args will be used
## by the first console only.
#set OPT(exec) {}
