Please help us by leaving a comment if you don't like our work.
This software is provided free, and is based on the labor of a number of individuals.
If it does not meet your needs, perhaps it was designed for a different purpose.
In any case, we cannot improve it to meet your needs if you don't give feedback other than a thumbs-down, as we cannot read your mind to know what you didn't like.
If you have a question on usage or construction, please email keller@cs.hmc.edu.
Thanks.
