# * **Watch out:** the Datomic command works only from the datomic_browser directory precisely. The `transactor` java process will resolve the config file path relative to the java resource path, or something. This is a common gotcha!
# * **Nix users**: user reports, "The transactor and the datomic bash files begin with an invalid shebang that only matters to nix people, see https://www.reddit.com/r/NixOS/comments/k8ja54/nixos_running_scripts_problem/"
