# This program archives the content of fandom wikis.
|
||||||
|
#
|
||||||
|
# It's pretty much feature-complete. I still have to add detailed comments to
|
||||||
|
# describe what each significant piece of code is doing.
|
||||||
|
#
|
||||||
|
# This program doesn't scrape from the fandom.com wiki sites directly; rather,
|
||||||
|
# it uses my BreezeWiki instance to avoid downloading unneccessary ads, images,
|
||||||
|
# and other junk.
|
||||||
|
#
|
||||||
|
# Each resulting archive is self-contained, meaning one can extract the
|
||||||
|
# contents and browse the wiki snapshot locally (offline). The URLs for CSS,
|
||||||
|
# images, and links in each page are replaced by the file:/// URLs for their
|
||||||
|
# corresponding pages on the local filesystem.
|
||||||
|
#
|
||||||
|
# This file is formatted with `black -l 79' to comply with PEP8 standards.
