 <p>The execve system call allows for another process to be &quot;called&quot; which will
 replace the current process image.  That is, this process becomes the new
 command that is run. On success, this function will not return. Instead,
 the new program will run until it exits.</p>

 <p>If an error occurs, this function will return with an indication of the
 cause of failure.  See
 <a href="http://man7.org/linux/man-pages/man2/execve.2.html#ERRORS">execve(2)#errors</a>
 for a list of potential problems that maight cause execv to fail.</p>

 <p><code>::nix::unistd::execv</code> and <code>::nix::unistd::execve</code> take as arguments a slice
 of <code>::std::ffi::CString</code>s for <code>args</code> and <code>env</code> (for <code>execve</code>). Each element
 in the <code>args</code> list is an argument to the new process. Each element in the
 <code>env</code> list should be a string in the form &quot;key=value&quot;.</p>
