Made example rockspec

[jprjr]

I just made an example rockspec file. This allows lua-zlib to be built and installed with luarocks build ./lua-zlib-git-2014.02.19-1.rockspec

I just merged this in: https://github.com/optiflows/lua-zlib/commit/33f2d8d6269ff84f6cd491dced567e38e0db5b72 can you compare this change with yours? I'm not to familiar with rockspec format.

Thanks,

Well, that other one is missing the flag for using the zlib library - check out lines 29-31 in my file.

The other thing is the source url and tag. You can use a git:// url as source.url and specify a tag with source.tag (I didn't do it that way in my rockspec, I just directly referenced a commit in source.url)
