====
<1> Apply the `base` plugin so that you'll have a `clean` task to use to remove the output.
<2> MD5 hash files will be written to `build/md5`.
<3> This task will generate MD5 hash files for every file in the `src` directory.

You will need some source to generate MD5 hashes from.
Create three files in the `src` directory:

.src/einstein.txt
