-- Hackage requires us to require Cabal-Version >=1.10; otherwise
-- things should be backwards compatible to >=1.2 (with the exception
-- of the tested-with and source-repository fields which were added
-- in >=1.6).
Cabal-Version:  >= 1.10
Build-Type:     Simple

Name:           unification-fd
Version:        0.11.0
Stability:      experimental

Category:       Algebra, Algorithms, Compilers/Interpreters, Language, Logic, Unification
Synopsis:       Simple generic unification algorithms.
Description:    Simple generic unification algorithms.

-- No longer compiles with GHC-6.12.1 since Data.Monoid does not
-- export (<>) in Control.Unification.Types. The backwards compatibility
-- is not considered worth adding CPP noise...
-- Last I checked, it also worked with 7.6.1 and 7.8.2; but I don't
-- have TravisCI enforcing those.
Tested-With:
    GHC == 7.4.2, GHC == 7.6.3, GHC == 7.8.4, GHC == 7.10.3, GHC == 8.0.2,
    GHC == 8.2.1, GHC == 8.2.2,
    GHC == 8.4.1, GHC == 8.4.2, GHC == 8.4.3, GHC == 8.4.4,
    GHC == 8.6.1, GHC == 8.6.2, GHC == 8.6.3, GHC == 8.6.4, GHC == 8.6.5,
    GHC == 8.8.1, GHC == 8.8.2, GHC == 8.8.3, GHC == 8.8.4,
    GHC == 8.10.1, GHC == 8.10.2, GHC == 8.10.3

Flag base4
    Default:     True
    Description: base-4.0 emits "Prelude deprecated" messages in
                 order to get people to be explicit about which
                 version of base they use.

Flag splitBase
    Default:     True
    Description: base-3.0 (GHC 6.8) broke out the packages: array,
                 bytestring, containers, directory, old-locale,
                 old-time, packedstring, pretty, process, random.
