+So, I like to see how much I'm getting for my $62 per month, so I wrote this script a long time ago to track upload, download and delay numbers across my Internet connection.
+It uses the node.js fast-cli script by Sindre Sorhus from [[https://github.com/sindresorhus/fast-cli|here]] or installed with ''%% npm install --global fast-cli %%''.
