--extra_lda_stopwords FILENAME

Description
===========

Path to a file of additional stopwords to remove before LDA topic estimation, on top of the automatically-detected ones.

Argument and Default Value
==========================

A file path. Default: ``None``.

Details
=======

Verified end-to-end with real Mallet: one word per line. Confirmed with a 2-word file (``love``, ``work``) — DLATK printed ``Removed an additional 2 extra stopwords: {'work', 'love'}`` alongside its own automatically-detected stopword list (frequent words/punctuation).

Optional Switches:
