#
# A script to ease the process of setting up users and WordPress installs
# in a test hosting environment. It does the following:
#
#    * Creates a user on the linux system with .ssh directory with the right privs
#    * Creates /var/www/html/$USERNAME and a symlink to /home/$USERNAME/wordpress
#    * Dumps WP 4.6 into the directory with passwords, etc., specified in the vars
#      below. 
#    * Creates the needed mysql database and privs.
#    * Adds custom salts to wp-config.php and runs the install script.
#
# The script doesn't do much validation and could be destructive. It's useful
# for bootstrapping a bunch of quick throwaway WP installs in a testing environment,
# but I wouldn't get anywhere near a production environment with this.
