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.
