# Pyenv Installer Script
#
# This script automates the installation of Pyenv and the latest Python versions
# on a Debian-based system or macOS. It installs necessary dependencies, sets up Pyenv,
# restarts the terminal, and installs the latest Python versions concurrently.
#
# Note: Ensure you have sudo privileges to install system dependencies.
#
# For more information on Pyenv, visit https://github.com/pyenv/pyenv
