Once again, I'd like to recommend the "SPDX License Diff" web browser extension 
for Chrome, Edge, Firefox, Opera:

	https://github.com/spdx/spdx-license-diff/releases/latest

or web stores:

https://chromewebstore.google.com/detail/spdx-license-diff/kfoadicmilbgnicoldjmccpaicejacdh

https://addons.mozilla.org/en-US/firefox/addon/spdx-license-diff

Display the licence in a web page, highlight the licence text to check, and 
click the icon to match against the latest SPDX database:

Submit new license

✔ BSD-2-Clause : 95.8% match (56 differences / dice-coefficient 0.97)
BSD 2-Clause "Simplified" License (BSD-2-Clause)✔
Good Match processed in 12.254s

Or copy/paste to the SPDX tool page:
