# Remote Bench Initialization Script for Frappe VPS
#=============================================================================
#
# Description:
#   Copies the bench initialization script and required files to the remote
#   server and executes it there. This handles the SSH connectivity and
#   remote execution automatically.
#
# Prerequisites:
#   - Dependencies setup completed
#   - SSH key authentication configured
#   - config.yml with site configuration
#
# What this script does:
#   1. Validates local configuration
#   2. Tests SSH connectivity to server
#   3. Copies bench init script and utilities to remote server
#   4. Executes bench initialization remotely
#   5. Cleans up temporary files
#
# Author: Generated for Frappe VPS Setup
# Dependencies: config.yml, utils.sh, bench_init.sh
#=============================================================================
