Looking at: http://gittup.org/tup/ex_dependencies.html http://gittup.org/tup/ex_dependencies.html I see the following warning about half way down the page. While I understand the first time this happens tup has an issue, I don't understand why it can't automatically remember it for future use (or does it?) *** tup errors *** tup error: Missing input dependency - a file was read from, and was not specified as an input link for the command. This is an issue because the file was created from another command, and without the input link the commands may execute out of order. You should add this file as an input, since it is possible this could randomly break in the future.
