examples/lib/fits.js download doesn't work

[cdeil]

This doesn't work for me:
https://github.com/astrojs/rawimage.js/blob/master/setup.sh#L9

I get an empty file:

$ curl  "https://raw.github.com/astrojs/fitsjs/rewrite/lib/fits.js" -o 'examples/lib/fits.js'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0

$ ls -l examples/lib/fits.js
-rw-r--r--  1 deil  staff  0 Jan  7 21:30 examples/lib/fits.js

This then leads to this error when I try to look at any of the examples:

Uncaught ReferenceError: astro is not defined
