# Simple helper to build the rfgrep snap locally.
# Requirements: snapcraft installed. For local builds use LXD; for cloud builds use `snapcraft remote-build`.
# Usage:
#   scripts/build_snap.sh            # try local build with LXD (default)
#   scripts/build_snap.sh remote     # use snapcraft remote-build
#   scripts/build_snap.sh lxd        # force local LXD build
