Ever since a0acb6956fdede396b814ce695eef78af0d56b96 was released, it became impossible for client applications to handle missing dependencies. If you're a rails app using this and you don't have a dependency that someone is looking for, your process will **abort**, which is not going to make your users happy.\r\n\r\n`raise`-ing an error generally returns a 1 exit code. Why is `abort` necessary?\r\n\r\nReal-life example: https://github.com/gjtorikian/jekyll-html-pipeline/pull/7#issue-126687668\r\n\r\n/cc @jch @simeonwillbanks who collaborated on #80."}}
