repo-pull.sh

#!/usr/bin/env bash
#-----------------------------------------------------------------------------------------------------------------------
# Description:  This script updates the repos necessary to build the TDS application.  Typically, this script will
# be run from the TDS_Build directory, which will create all of the cloned repos in tds-build's sibling repositiries
# directory. It leverages the same clone-repos.txt file for the project information.
# Unlike repo-update.sh this will pull the latest remote origin changes on the current branch rather than checking
# out a specific branch for each repository.
#
# Pre-requisites:  Git, a file list of repos,  ssh keys
#
# Usage:
#   ./repo-pull.sh
#
