Readme for hprotoc-2.0.14
To regenerate the plugin haskell files, please run
hprotoc -u --prefix=Text -d protoc-gen-haskell -I google-proto-files/ google/protobuf/plugin.proto
This was last populated from version 2.4.0a of Google's code.
Also, one can invoke cabal build to make dist/autogen and then
ghci -package parsec-2.1.0.1 -idist/build/autogen -iprotoc-gen-haskell Text/ProtocolBuffers/ProtoCompile.hs
should work.
