# How to set these variables:
#
# GitHub_Owner
# GitHub_Repo 
#
# Example use:
#
# The Linde Group has repos on GitHub available
# via https://github.com/lindegroup
# To set the Linde Group as the owner, 
# set the following:
# GitHub_Owner="lindegroup"
#
# If you want to get the latest release of 
# the Linde Group's AutoPkgr software, the
# repo which has AutoPkgr is named "autopkgr".
# The Linde Group has set up releases for AutoPkgr,
# so set the following:
# GitHub_Repo="autopkgr"
#

GitHub_Owner="repo_owner_goes_here"
GitHub_Repo="repo_name_goes_here"

# Specify a directory in /tmp to store the downloaded file
download_location=`/usr/bin/mktemp -d /tmp/$GitHub_Repo.XXXX`

GitHubProjectLatestRelease=$(/usr/bin/curl --silent https://api.github.com/repos/$GitHub_Owner/$GitHub_Repo/releases/latest | /usr/bin/awk '/browser_download_url/ { print $2 }' | /usr/bin/sed 's/"//g')

# Download latest release to the specified location in /tmp

cd $download_location;/usr/bin/curl -LOk "$GitHubProjectLatestRelease"
echo "Downloaded file is stored in $download_location."
