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