Description:
  Performs setup of the dependent packages used in the FLiT
  tutorial examples.  It will download and configure MFEM and
  LULESH with their respective dependencies.

  This script does not download or install FLiT.  That can be done
  simply with

    $ git clone https://github.com/PRUNERS/FLiT.git
    $ make --directory FLiT

  The installation documentation can be found in

    FLiT/documentation/installation.md

Options:

  -h, --help   Print this help documentation and exit
  -f, --force  Force setup script to run even if it was previously successful
