description:
    <https://github.com/snowleopard/alga Alga> is a library for algebraic construction and
    manipulation of graphs in Haskell. See <https://github.com/snowleopard/alga-paper this paper>
    for the motivation behind the library, the underlying theory and implementation details.
    .
    The top-level module
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph.html Algebra.Graph>
    defines the main data type for /algebraic graphs/
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph.html#t:Graph Graph>,
    as well as associated algorithms. For type-safe representation and
    manipulation of /non-empty algebraic graphs/, see
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-NonEmpty.html Algebra.Graph.NonEmpty>.
    Furthermore, /algebraic graphs with edge labels/ are implemented in
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-Labelled.html Algebra.Graph.Labelled>.
    .
    The library also provides conventional graph data structures, such as
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-AdjacencyMap.html Algebra.Graph.AdjacencyMap>
    along with its various flavours: adjacency maps specialised to graphs with
    vertices of type 'Int'
    (<http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-AdjacencyIntMap.html Algebra.Graph.AdjacencyIntMap>),
    non-empty adjacency maps
    (<http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-NonEmpty-AdjacencyMap.html Algebra.Graph.NonEmpty.AdjacencyMap>),
    and adjacency maps with edge labels
    (<http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-Labelled-AdjacencyMap.html Algebra.Graph.Labelled.AdjacencyMap>).
    A large part of the API of algebraic graphs and adjacency maps is available
    through the 'Foldable'-like type class
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-ToGraph.html Algebra.Graph.ToGraph>.
    .
    The type classes defined in
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-Class.html Algebra.Graph.Class>
    and
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-HigherKinded-Class.html Algebra.Graph.HigherKinded.Class>
    can be used for polymorphic construction and manipulation of graphs. Also see
    <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-Fold.html Algebra.Graph.Fold>
    that defines the Boehm-Berarducci encoding of algebraic graphs.
    .
    This is an experimental library and the API is expected to remain unstable until version 1.0.0.
