    // The mergeWith() rule merge two trees; one that's coming from a Source (a Tree with no
    // base), and the one as input to the rule. You can think of it like rebasing a Source on
    // top of your current set of changes. In this case, the Source is that apply function.
    // The apply() source takes a Source, and apply rules to it. In our case, the Source is
    // url(), which takes an URL and returns a Tree that contains all the files from that URL
    // in it. In this case, we use the relative path `./files`, and so two files are going to
    // be created (test1, and __name@dasherize__.md).
    // We then apply the template() rule, which takes a tree and apply two templates to it:
    //   path templates: this template replaces instances of __X__ in paths with the value of
    //                   X from the options passed to template(). If the value of X is a
    //                   function, the function will be called. If the X is undefined or it
    //                   returns null (not empty string), the file or path will be removed.
    //   content template: this is similar to EJS, but does so in place (there's no special
    //                     extension), does not support additional functions if you don't pass
    //                     them in, and only work on text files (we use an algorithm to detect
    //                     if a file is binary or not).
