"""_Matthew 25:30 is the title of both a computer program, the source code
to which you may be reading, and the output of this program, which in
many ways is like a standard novel or poem and which you may instead be
reading. This note appears at the beginning of both.

To produce markdown output, run matthew.py (Python 2) with TextBlob.

    % python matthew.py > matthew.text

To produce PDF and epub documents, use pandoc:

    % pandoc -V geometry:paperwidth=5.5in \
        -V geometry:paperheight=8.25in \
        -V geometry:margin=.75in -o matthew.pdf \
        matthew.text
    % echo '% Matthew 25:30' > info.txt
    % echo '% Nick Montfort' >> info.txt
    % pandoc -o matthew.epub info.txt matthew.text

_Matthew 25:30_ was written/generated for the third NaNoGenMo (National
Novel Generation Month) in November 2015, and is free software."""

a clamor of trains that weave iron mazes.
Steam and shrieks ascend the morning,

the ultimate sale, the blackest Friday. From the obscured
horizon and from the center of my being, an infinite voice
said these things (these actual stock-keeping units,
not the words that follow, which are but my poor time-bound
translation of what was a single word):
