Broken external links in Tech Note and User's Guide

[samsrabin]

Many. To check them on a Mac, here's a bash one-liner that will open all the URLs in the .rst files in our doc/ directory:

open $(grep -hEo "(http|https)://[\#a-zA-Z0-9./?=_%:-]*[^.>;\),/]" $(find doc -name "*rst") | sort -u | sed "s/]//g")

Note that this is distinct from Issue #2541, which has to do with within-documentation links in the sidebar.

Also note that this issue does not include the broken links noted in its sibling issue #3192.

curl -s -o /dev/null -w "%{http_code}" $URL will return something other than 200 if the page doesn't exist. That will enable programmatic checking so we don't have to actually look at every site (although it might be good to do that as a second step).
