The module polyseq-0.1.2 can be installed the following way: runhaskell Setup.hs configure --user runhaskell Setup.hs build runhaskell Setup.hs haddock runhaskell Setup.hs install runhaskell Setup.hs haddock builds the documentation. This step is not necessary. After installation the modules Language.Haskell.FreeTheorems.Variations.PolySeq.PolySeq Language.Haskell.FreeTheorems.Variations.PolySeq.PrettyPrint Language.Haskell.FreeTheorems.Variations.PolySeq.TypeTranslator Language.Haskell.FreeTheorems.Variations.PolySeq.TheoremGen Language.Haskell.FreeTheorems.Variations.PolySeq.Parser.ParseTerm are available. To start the webinterface do $ ./test.sh then it runs under http://localhost:8002/ The webinterface can also be found under http://www-ps.iai.uni-bonn.de/cgi-bin/polyseq.cgi Enjoy. Acknowledgements. ================= Most of the webinterface' code (./src/polyseq-cgi.hs) and the script testcgi.py are written by Joachim Breitner . Thanks!
