synopsis: "Coq library and tactic for deciding Kleene algebras"
description: """
This library provides algebraic tools for working with binary relations.
The main tactic provided is a reflexive tactic for solving (in)equations
in an arbitrary Kleene algebra. The decision procedure goes through
standard finite automata constructions.
Note that the initial authors consider this library to be superseded
by the Relation Algebra library, which is based on derivatives
rather than automata: https://github.com/damien-pous/relation-algebra"""

trueDry install with the current Coq version:
opam install -y --show-action coq-atbr.8.11.0 coq.8.9.0[NOTE] Package coq is already installed (current version is 8.9.0).
The following dependencies couldn't be met:

Your request can't be satisfied:
- No available version of coq satisfies the constraints
No solution found, exiting
Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
opam remove -y coq; opam install -y --show-action --unlock-base coq-atbr.8.11.0truetrueNo files were installed.
