You'd think a site who's business model hinged on scraping others
would be a little more scraper-friendly.

Now I can't use Google cache even manually.

Here's what I did:
- query "site:wiki.alu.org"
- save the 4 pages as wiki1.html, wiki2.html, ...
- run `./pull.sh wiki1`

# pull.sh
cat <<_EOF > pull.sh
#!/bin/bash

page=$1 # e.g. wiki1

rm -rf $page
mkdir $page
sed -e 's,<a ,\n<a ,g' $page.html | grep Cached > $page/links.txt
cd $page
sed -e 's,<a href=",,' -e 's,\+site.*,,' links.txt > urls.txt
for f in $(<urls.txt)
do
     name=`echo $f | sed -e 's,.*:wiki.alu.org/,,'`
     wget -U nuweb -O $name $f
done
_EOF

When I try again later, I'll pass wget an extra "-w 10 --random-wait"
to try and stay below their radar.  Also change "nuweb" to some other
user-agent string (in case they remember).
