[terceiro]

Used transpec and a did a few manual tweaks

Hello @brynary
I want you to merge this pull-request to master branch, as I want to use Rspec3.

@junaruga This one we shoud rebase on top of latest master, would be great to be able to use a current rspec with the project.

this port has been made more or less obsolete by commit 7536f85

I will just close this.

FTR, merging people's contributions with no attribution whatsoever is not a very nice thing to do. I am an old fart and don't really care in the long run, but I imagine someone new to free software/open source would be really bombed out by that.

[perlun]

@terceiro You're right, sorry about that. The project had gotten unmaintained for various reasons and @scepticulous did a catchup PR in #141. I rebased these commits onto current master when the repo was moved to the rack-test organization.

If you like, you can update the README.rdoc list of authors to include your name and submit a PR; I'll gladly accept it.

@perlun we have already supported rspec3 by below commit that you had merged.

@junaruga Yes, I realize that, my bad. 😄

@perlun no worries. thanks for stepping up to maintain this in the first place!
