# pipe-by-by rundown:
# Fetch & Clean Article
# 1: lynx: dump contents of URL
# 2: awk: clear all lines less than 10 words long (assume shorter lines are links/navigation/etc, and longer lines are content)
# 3: sed: remove lynx-syntax images
# 4: sed: normalize multiple whitespace characters
# 5: grep: only keep letters ' and -
# Put in bag & Shake
# 6: snuf: shuffle lines
# Pull out words (not quite one-at-a-time, but forced into the shape of a poem)
# 7: tr: convert to one long line
# 8: fold: fold text into lines 60-100 characters long (mindful not to split words)
# 9: shuf: shuffle lines, only return 3-10 of them
# 10: fold: fold text into lines 13-30 characters long (mindful not to split words)
# 11: sed: split text into stanzas 3-6 lines long
