 * Q: Can I use the system ``man`` command instead of ``cppman``?
 * A: Yes, just execute ``cppman -m true`` and all cached man pages are exposed to the system ``man`` command.  Note: You may want to download all available man pages with ``cppman -c``.
 * Q: Why is bash completion is not working properly with ``::``?
-* A: It is because bash treats ``:`` like a white space. To fix this add ``export COMP_WORDBREAKS=" /\"\'><;|&("`` to your ``~/.bashrc``.
