Requirements

Flow requires a Haskell compiler. It is tested with recent versions of GHC, but older or different compilers should be acceptable. For installation with Cabal, Flow requires at least Cabal 1.8.

Installation

To add Flow as a dependency to your package, add it to your Cabal file.

build-depends: flow ==1.0.*

See the change log for a detailed list of changes.

Usage

Flow is designed to be imported unqualified. It does not export anything that conflicts with the base package.

import Flow
