# Cron job command for Laravel 4.2
# Inspired by Laravel 5's new upcoming scheduler (https://laravel-news.com/2014/11/laravel-5-scheduler)
#
# Author: Soren Schwert (GitHub: sisou)
#
# Requirements:
# =============
# PHP 5.4
# Laravel 4.2 ? (not tested with 4.1 or below)
# A desire to put all application logic into version control
#
# Installation:
# =============
# 1. Put this file into your app/commands/ directory and name it 'CronRunCommand.php'.
# 2. In your artisan.php file (found in app/start/), put this line: 'Artisan::add(new CronRunCommand);'.
# 3. On the server's command line, run 'php artisan cron:run'. If you see a message telling you the
#    execution time, it works!
# 4. On your server, configure a cron job to call 'php-cli artisan cron:run >/dev/null 2>&1' and to
#    run every five minutes (*/5 * * * *)
# 5. Observe your laravel.log file (found in app/storage/logs/) for messages starting with 'Cron'.
#
# Usage:
# ======
# 1. Have a look at the example provided in the fire() function.
# 2. Have a look at the available schedules below (starting at line 132).
# 4. Code your schedule inside the fire() function.
# 3. Done. Now go push your cron logic into version control!
