From 31d78619092ba930f94f19599a677842ca66d216 Mon Sep 17 00:00:00 2001
From: Martin Kulhavy <martin.kulhavy@nokia.com>

Subject: Move help usage information to beginning of script

If user requests the usage information (e.g. with `--help` argument),
the information should be displayed right away. Currently the script
first runs updates and installs of dependencies, which can take very
long time.
