# Install parameters are automatically saved as settings

# Settings are automatically loaded as bash variables
# in every app script context, therefore typically these will exist:
# - $domain
# - $path
# - $language
# ... etc
#
# Resources defined in the manifest are provisioned prior to this script
# and corresponding settings are also available, such as:
# - $install_dir
# - $port
# - $db_name
# ...

#
# $app is the app id (i.e. 'example' for first install, 
# or 'example__2', '__3', ... for multi-instance installs)
