[Cook] Aborting a cook invocation

[Jody Hagins]

I want to exit gracefully from a cook invocation under certain cases. 
For example, assume I want a variable to be set on the command line when
cook is invoked.  I would like to do something like this...



if [not [defined variable_y]] then
{
  echo "variable_y is not defined!" set silent;
  exit 1;
}


But, there is no exit function, and I do not see a way of gracefully
aborting.


Thanks for any assistance!
