  77 Tips to prevent and resolve:
  78 * Enable WITH_ASTYLE in your cmake configuration to format C++ code
  79 * Install autopep8 (>= 1.2.1) to format python code
  80 * Use "scripts/astyle.sh file" to fix the now badly indented files
  81 * Consider using scripts/prepare-commit.sh as pre-commit hook to avoid this
  82   in the future (ln -s scripts/prepare-commit.sh .git/hooks/pre-commit) or
  83   run it manually before each commit.
