  * **`--nowait`** : When executed from a new X11 terminal, disable the user prompt at the end of the script execution.
  * **`--nomd5`** and **`--nocrc`** : Disable the creation of a MD5 / CRC checksum for the archive. This speeds up the extraction process if integrity checking is not necessary.
  * **`--sha256`** : Adds a SHA256 checksum for the archive. This is in addition to the MD5 / CRC checksums unless `--nomd5` is also used.
- * **`--lsm` _file_** : Provide a Linux Software Map (LSM) file to makeself, that will be embedded in the generated archive. LSM files are describing a software package in a way that is easily parseable. The LSM entry can then be later retrieved using the `--lsm` argument to the archive. An example of a LSM file is provided with Makeself.
