# This script installs rssx on Linux and macOS.
#
# Usage:
#   curl -fsSL https://raw.githubusercontent.com/l-z-h/rssx/main/scripts/install.sh | sh
#
# The script will:
# 1. Detect the user's OS and architecture.
# 2. Download the latest release of rssx for their platform.
# 3. Extract the binary and move it to /usr/local/bin (with sudo) or ~/.local/bin.
# 4. If installed to ~/.local/bin, it will add the directory to the user's PATH.
