bugprone-command-processor
==========================

Flags calls to ``system()``, ``popen()``, and ``_popen()``, which
execute a command processor. It does not flag calls to ``system()`` with a null
pointer argument, as such a call checks for the presence of a command processor
but does not actually attempt to execute a command.
