# Script to initialize a system into Ansible collection.

## Global Variables ##

PROG=`basename $0`
LOCAL=`dirname $0`/local.yml
URL="https://github.com/Hyperling/ansible"
BRANCH="main"

## Functions ##

# Accepts 1 parameter, it is used as the exit status.
function usage {
	cat <<- EOF

	  $PROG [-l] [-b branch_name] [-h]
	    Program to initialize synchronization with Hyperling's Ansible configuration.
	      $URL

	    Parameters:
	      -l : Run the local playbook associated with this $PROG. 
	             This is helpful for development or just saving bandwidth.
	             It also provides prettier colors than the plaintext from ansible-pull. ;)
	      -b branch_name: Download and run a specific branch. Default is $BRANCH.
	      -h : Display this help text
	
	EOF
	exit $1
