ClioPatria relies on two external executables that are not standard available on Windows: git.exe for providing version information and dot.exe, part of GraphViz for rendering graphs.
These programs must either be in %PATH% or made accessible through file_search_path/2. The latter can be by means of hard-coded paths or using the dynamic approach implemented below. This hopefully works out-of-the-box in most installations. If it fails for you, please help improving this config and/or add a hard-coded location. See the example below.
