This package discusses issues with Copilot and includes documentation.
Copilot is a stream (i.e., infinite lists) domain-specific language (DSL) in Haskell that compiles into embedded C. Copilot is similar in spirit to languages like Lustre. Copilot contains an interpreter, multiple back-end compilers, and other verification tools.
Please see the files under the Examples directory in the Copilot for a number of examples showing the syntax, use of libraries, and use of the interpreter and back-ends. The examples is the best way to start.
copilot-discussion is available on Hackage.
Sources for each package are available on Github as well. Just go to Github and search for the package of interest. Feel free to fork!
Copilot is distributed with the BSD3 license. The license file contains the BSD3 verbiage.
