[telemachos]

I agreed with the people saying that a confirmation before uploading would be helpful, so I went to file an issue.

It turns out there is one there already. You can weigh in here: https://github.com/ConradIrwin/showterm/issues/12.

EDIT: A follow up: It turns out that there is a slightly hidden and indirect way to abort uploads. Start the program as `showterm -e`, and it will offer you a chance to edit timings before uploading. (This is intended to give you a chance to trim out long pauses.) At that point, if you can cause your editor to abort with a non-zero status, the upload aborts. For Vim users, the gem's author points to exiting with `:cq`.
