 The CodeHawk-C Analyzer consists of two parts:

-Alternatively, you can edit the path to these two executables directly

+You can either:
+- Copy `chc/util/ConfigLocal.template` to `chc/util/ConfigLocal.py`
+in this repository, and edit the latter file to set the paths for
+`config.canalyzer` and `config.cparser` to the `dune`-built binaries,
+which should be in `your-path-to-codehawk/CodeHawk/_build/install/default/bin/`.
+This allows CodeHawk-C to automatically use newly-built versions of the
+OCaml analyzer.
+- Or, you can copy the `canalyzer` and `parseFile` binaries from that location
+into `chc/bin/linux/` or `chc/bin/macOS` within this repository.
+To allow CodeHawk-C to use newly-built versions of the OCaml analyzer,
+you will have to re-copy the binaries after every build.
