# This script "powers up" a cakephp site by checking out the code from the
# git repository and installing the composer dependencies.
# This script is currently highly specific to site avenger.

# General Info:
#
# The naming scheme here is a little complex, but it's basically this...
# A git repository is expected to be provided, and we will get all the code
# for the web site from there.  The repository is expected to have a single
# application "name" and one or more "themes".  By convention, the name
# and the theme are often the same, except the theme is capitalized.
# For example, let's say our app name is "turtle" and our theme name is "box".
# The repo is checked out to a folder called "~/apps/turtle".
# This script will want to use "turtle" as the app name.
# It will have to be told the theme name, but will assume it's 'Turtle' to
# start with.  The concept of the theme comes from cakephp.

export THISDIR="$( \cd "$(\dirname "$0")" && \pwd )"  # obtain the script's working directory.
export FEISTY_MEOW_APEX="$( \cd "$THISDIR/../.." && \pwd )"
