;;; Commentary:
;;
;; This file provides commands useful for debugging project configuration
;; issues when breakpoints or sourcemaps do not work.
;;
;; - `indium-list-sourcemap-sources': List all sourcemap sources, as resolved to
;; disk files. This commands helps understanding how Indium maps sourcemaps to
;; file paths using the `.indium.json' project file.
;;
;; - `indium-list-script-sources': List all script parsed by the backend. Their
;; source file is resolved to a file on disk when possible.
