val prefix_t : Fpath.t Term.t
val exec_dir : Fpath.t

Directory containing dkml-package.bc or whatever executable (perhaps a renamed setup.exe in a non-bin folder) is currently running.

val enduser_archive_dir : unit -> Fpath.t Dkml_install_api.Forward_progress.t

The root directory that was uncompressed at end-user install time

val staging_default_dir_for_package : archive_dir:Fpath.t -> Fpath.t

staging_default_dir_for_package ~archive_dir. For the benefit of Windows and macOS we keep the directory name ("sg") small.

val static_default_dir_for_package : archive_dir:Fpath.t -> Fpath.t

static_default_dir_for_package ~archive_dir. For the benefit of Windows and macOS we keep the directory name ("st") small.

staging_files_source_for_package_t is the setup.exe/uninstall.exe Term.t for the staging files directory. It defaults to the sibling directory "staging".

static_files_source_for_package_t is the setup.exe/uninstall.exe Term.t for the static files directory. It defaults to the sibling directory "static".

ctx_for_runner_t component_name reg creates a user.exe/admin.exe Term for component component_name that sets up logging and any other global state, and defines the context record.

The package (setup.exe/uninstall.exe) will typically use sudo on Unix or gsudo on Windows to elevate the privileges of `admin.exe`. However it is very unlikely that the environment variables are propagated from the user (setup.exe) to the elevated process (admin.exe). So the staging directory must be specified (`No_staging_default`) when the runner user.exe/admin.exe is launched.

That is, the user process setup.exe can pass its environment variable OPAM_SWITCH_PREFIX (if specified with the no argument `--opam-context` option of setup.exe) into the staging directory argument for admin.exe.

ctx_for_package_t component_name reg creates a setup.exe/uninstall.exe Term for component component_name that sets up logging and any other global state, and defines the context record.

Unlike ctx_for_runner_t the expectation is that setup.exe/uninstall.exe will be directly launched by the user and have access to the user's environment variables, especially OPAM_SWITCH_PREFIX. So the no argument --opam-context option of setup.exe can default to OPAM_SWITCH_PREFIX.

Unlike ctx_for_runner_t the staging directory has a default (`Staging_default_dir`) based on relative paths from setup.exe.
