libghc-ranged-sets-dev 0.3.0-5build3 (amd64 binary) in ubuntu utopic

 A ranged set is an ordered list of ranges. This allows sets such as all
 reals x such that:
 .
 (0.25 < x <= 0.75 or 1.4 <= x < 2.3 or 4.5 < x)
 .
 Alternatively you can have all strings s such that:
 .
     ("F" <= s < "G")
 .
 This package provides a library for the Haskell programming language.
