As a person who wants to allow other people to use my code, I want to use a standard, proper license. But sometimes my code ends up being smaller than the LICENSE file that comes with it. This can especially annoying if I write a code snippet and want people to actually use it. I don't especially like the idea of copying and pasting 196 words of the MIT License, and then 30 words of the actual code itself. That just sounds absurdly wasteful.
Could I just mention that my code is under the MIT License (or any license for that matter) and then simply give a person the link to that license, so they can look at its terms and conditions?
