+#   Usage:
+#
+#        Check package v3.0.0 availability for all platforms, no auth required:
+#            > ./package_check.sh 3.0.0
+#
+#        Check pkgs and download if present, with authentication:
+#            > CERT=<cert-path> KEY=<key-path> DL=1 ./package_check.sh 3.0.0
+#
+#        Required parameters:
+#
+#            version: the version of agent you wish to search for i.e 3.0.0
+#
+#        Optional parameters:
+#
+#            PKG_REPO: The root url for the repository you wish to check, defaults to packages.nginx.org
+#            CERT: Path to your cert file
+#            KEY: Path to your key file
+#            DL: Switch to download the package if it is present, set to 1 if download required, defaults to 0
+#
+#   Packages are downloaded to the local directory with the path of its corresponding repo url + uri i.e
+#
+#            packages.nginx.org/nginx-agent/debian/pool/agent/n/nginx-agent/nginx-agent_3.0.0~bullseye_arm64.deb
