usage: ${0##*/} [OPTION]

options:
  -force        Force overwrite of existing tutorialsTest directory
  -debug        Adjust DebugSwitches (fvSchemes, solution)
  -default      Sets up a default scheme on all schemes
  -git          Use git to retrieve the tutorials
  -no-git       Do not use git to retrieve the tutorials
  -root=DIR     Root directory to start tests from (non-git only)
  -help         Print the usage

Quickly tests the tutorials and writes out the scheme/solver information.
Detects and uses 'git' to obtain a fresh set of files when possible.
