#
# Clones a Git repository from an Acquia Cloud remote URL.
#
# This script is typically used during the `lando init --source acquia` process.
# It handles setting up SSH for Git operations by using a specified key,
# waits for the key to be recognized by Acquia Cloud, and then clones
# the repository using the provided URL and options.
#
# Arguments:
#   $1: The Git repository URL to clone (e.g., user@server:repo.git).
#   $2: Optional Git clone options (e.g., "--branch main", "--depth 1").
#       If empty or "" (an empty quoted string), no options are used.
#   $3: The name of the SSH private key file (without path) located in /lando/keys/
#       to be used for authentication.
#
# Example usage:
#   /scripts/acquia-clone.sh git@github.com:user/repo.git "--branch develop" my_acquia_key
#
