- `-n/--name [function]`, output the name of a function, and ask for permission to have its dependencies installed.
- `-n/--name [function]`, output the name of a function that calls for the installation/update of given packages, and ask for permission to have them installed/updated.
- `-f/--force [package]`, when uninstalling a package, do so by simply deleating its executable file.
- `-f/--force [package]`, when uninstalling a package, do so by simply deleating its binary.

## Disclaimer
> This script has only been tested on Termux and some Debian-based operating systems, both of which use the `apt` package manager by default. The commands for verification, installation, updating and uninstallation of other default package managers have been drawn from reference. If you experience problems using this script wih your default package manager, issue reports and pull requests will be most welcome.
