packages: The input package names.
exports: Named list mapping package names to character vectors of exported function names (from collect_pkg_funs()).
export_index: Named list mapping function names to character vectors of packages (from build_export_index()).
origin_map: Environment mapping "pkg::fun" keys to origin packages (from build_origin_map()).
pkg_versions: Named list mapping package names to version strings.

Examples

build_universe_data(c("stats", "utils"))
