A set with the key names being the environment variable you'd like to
set and the values being a list of paths to text documents containing
lists of words. The various files will be merged, sorted, duplicates
removed, and extraneous spacing removed.
If you have a handful of words that you want to add to an already
existing wordlist, you may find `builtins.toFile` useful for this
task.
