Argh… I hate that it sounds so “unpoetic” the last parts… so if you enjoy to write it. See if you can work that into a third verse.

Oh… I’ll gladly insert a copy (or a link) - whatever you require, of your original poetic license.

Point well taken. I would not like to sit on a corporate committee deciding upon such trite things.

However, one advantage of this poem is that it is memorable and thus understandable. I think the spirit of the letter will come through. And as for proliferation, it is hardly different than MIT, ISC, or the thousands of other BSD derivatives.

As lame as the poem may be, I predict it has greater coalising power than any other BSD derivatives and may thus serve to reduce licensing proliferation.

Cheers,

The purpose of a license, though, must primarily be to grant license to the recipient. For this purpose, legal robustness, standing diverse tests over time, must surely be of greater value than poetic beauty or entertainment value.

Please, when choosing a license for a work, don’t exacerbate the proliferation of licenses http://www.opensource.org/proliferation

Instead, please choose a widely-studied license known in the community to result in robust grant of freedoms. licensing@fsf.org
