Include license in gem

[marvinthepa]

why?

1. Redistributions of source code must retain the above copyright

2. Redistributions in binary form must reproduce the above copyright

AFAIK, a gem is a redistribution of source code and/or binary formats, so it should include the license. Also makes it easier for users of the gem to compile a list of all licenses they use.

Good catch!
Could you also add COPYING?

Could you also add COPYING?

With the greatest pleasure.

Copying seems to contain a two contradictions, though:

• it is copyrighted to Minero Aoki, while LICENSE.txt is copyrighted to Yukihiro Matsumoto
• it mentions the file BDSL, which does not exist (should probably refer to LICENSE.txt, as this contains the mentioned 2-clause BSD license)

I do not feel like I should fix these issues, so I will just add the file.

OK. I'll merge this as is.

Thanks.
