# Meridian — Compatibility shim
#
# This script installs the `meridian` CLI and guides users to the new interface.
# The old `curl setup.sh | bash` pattern is replaced by:
#
#   curl -sSf https://getmeridian.org/install.sh | bash
#   meridian setup 1.2.3.4
#
# For backward compatibility, this script still works:
#   curl -sS https://getmeridian.org/setup.sh | bash
