libghc-topograph-dev - 1.0.0.2-1+b1 main

Directed acyclic graphs can be sorted topographically.
Existence of topographic ordering allows writing many graph
algorithms efficiently. Many graphs, including most
dependency graphs, are acyclic.
.
There are some algorithms built in: dfs, transpose, transitive
closure, transitive reduction, etc.
.
This package provides a library for the Haskell programming language.
