Hibernate Setup

A Python-based utility for configuring hibernation on Linux systems using a swap file. This tool automates resume configuration for GRUB and initramfs and optionally creates a swap file of configurable size.

Designed for Arch-based systems (Arch Linux, Manjaro) and intended for automation and reproducible system setup.
