 ## Input and conversion
 
-Use a clean ELF executable. Place its bundled ELF modules in `sce_module/`, `sce_modules/`, or `prx/` under the current working directory, or under the parent directory selected with `--sce-module-path <path>`. The option accepts absolute paths and paths relative to the current working directory; do not include the `sce_module` directory itself. Only files directly inside the module directories are processed. A bundled module in a SELF container is an error, as the executable is. `prx/` can coexist with either `sce_module/` or `sce_modules/`. Both `sce_module/` and `sce_modules/` present, or all three absent, is an error.
