# bootstrap-linux.sh [<SDPBranch> [<HelixInstallerBranch>]]
# The <SDPBranch> parameter (must be first argument) and
# <HelixInstallerBranch> parameter (must be second argument)
# are optional.  SDPBranch determines the branch of the
# SDP to test with, 'main' by default but can be 'dev'.  The
# HelixInstallerBranch is auto-detected based on the current
# directory if possible, otherwise 'dev' by default, but can
# be 'main'.

# Bootstraps a new Linux server with requirements Helix Installer testing.
