# This script scrapes the Covid-19 Wikiproject
|
|
#
|
|
# It (1) hits the fcgi to find out how many rounds. Then (2) hit the fcgi
|
|
# that many rounds, cooking that information down to just a list of article names and
|
|
# then (3) saves it out.
|
|
#
|
|
# At time of writing:
|
|
# the fCGI returns only 1000 max, no matter what you put in the limit. page 1 looks like this....
