alf
0.10.0
Alf brings the relational algebra both in Shell and in Ruby. In Shell, because manipulating any relation-like data source should be as straightforward as a one-liner. In Ruby, because I've never understood why programming languages provide data structures like arrays, hashes, sets, trees and graphs but not _relations_... Let's stop the segregation ;-)
