synopsis:            Visualize Haskell data structures as edge-labeled trees
description:         The tracetree library can be used to conveniently write
                     Haskell data structures as trees represented as JSON
                     files. These JSON files can then be inspected with any
                     JSON viewer; the JSON viewer's functionality to collapse
                     part of the JSON tree can be particularly convenient when
                     exploring large objects.
                     .
                     Additionally, the ttrender executable can be used to render
                     these JSON trees as .svg or .png files, and provides
                     various command line flags for controlling the layout of
                     the tree (colour, orientation, hiding nodes, etc.).
                     .
                     The tracetree library and ttrender executable are
                     independent components; if you don't want to add the
                     dependency on tracetree to your project, you can just
                     generate the .JSON files directly in your code; the format
                     is not complicated (indeed, you can create them by hand
                     or post-process previously exported .JSON files).
