Usage: install-perfsonar [ OPTIONS ] BUNDLE [ URL ... ]

BUNDLE is one of tools, core, testpoint, toolkit or archive.

URL points to a pSConfig file that will be applied with 'psconfig
remote add' if pSConfig is installed.

OPTIONS:

  --add P               Add package P to the installation.  May be
                          used repeatedly for multiple packages.
  --auto-updates        Enable automatic updates
  --security            Install security package
  --tunings             Install system tunings
  --repo R              Use repository R (production, staging,
                          nightly-minor or nightly-patch).  Defaults
                          to production.
  --dry-run             Don't do anything
  --no-log              Don't write a log into $HOME
  --ps-repo-version V   Use perfSONAR repo verion V on EL systems

NOTE:

  The --security and --tunings switches are for the testpoint and
  toolkit bundles only.

Example usage from GitHub:

  curl -s https://raw.githubusercontent.com/perfsonar/project/master/install-perfsonar \
    | sh -s - --auto-updates --tunings testpoint
