# Script to build a Slackware .txz package for snapraid
# using the snapraid.SlackBuild and related files in the current directory.
#
# This version:
# - Prefers a source tarball already present in the current directory
# - Only downloads it if not found locally
# - Runs the SlackBuild (as root recommended for makepkg)
#
# Requirements:
# - Run as root (or with sudo) for proper ownership/permissions in package
