A self-extracting archive is a custom script that installs a program. These are given the .run extension as a formality. Users can install them through the terminal like so:

This will install your program to /opt/<package>/, where <package> is the value of the package key in the packthing.yml file.

This packager creates a standalone release, building executables as static where supported and bundling dependencies. An uninstaller is not created; remove /opt/<package>/ to uninstall.
