Consider adding a license

[fmbarina]

This is probably an unnecessary question considering the nature of the repository (a funny bash cat), but is it okay to copy/redistribute the script? In a personal dotfiles repo, for example.

I imagine you wouldn't mind, but if that's the case, would you consider adding a license to make that explicit? If you don't want to attach your name to the project so strongly, you could use something like the unlicense.

Thanks for writing this, anyway. The cat is pretty funny.
