534  *
535  * @cfgcmd{nodaemon}
536  * Do not fork or background the VPP process. Typically used when invoking
537  * VPP applications from a process monitor.
538  *
539  * @cfgcmd{exec, &lt;filename&gt;}
540  * @par <code>startup-config &lt;filename&gt;</code>
541  * Read startup operational configuration from @c filename.
542  * The contents of the file will be performed as though entered at the CLI.
543  * The two keywords are aliases for the same function; if both are specified,
544  * only the last will have an effect.
545  *
546  * @cfgcmd{log, &lt;filename&gt;}
547  * Logs the startup configuration and all subsequent CLI commands in
548  * @c filename.
549  * Very useful in situations where folks don't remember or can't be bothered
550  * to include CLI commands in bug reports.
551  *
552  * @cfgcmd{pidfile, &lt;filename&gt;}
553  * Writes the pid of the main thread in @c filename.
554  *
555  * @cfgcmd{full-coredump}
556  * Ask the Linux kernel to dump all memory-mapped address regions, instead
557  * of just text+data+bss.
558  *
559  * @cfgcmd{runtime-dir}
560  * Define directory where VPP is going to store all runtime files.
561  * Default is /run/vpp.
562  *
563  * @cfgcmd{cli-listen, &lt;address:port&gt;}
564  * Bind the CLI to listen at the address and port given. @clocalhost
565  * on TCP port @c 5002, given as <tt>cli-listen localhost:5002</tt>,
566  * is typical.
567  *
568  * @cfgcmd{cli-line-mode}
569  * Disable character-by-character I/O on stdin. Useful when combined with,
570  * for example, <tt>emacs M-x gud-gdb</tt>.
571  *
572  * @cfgcmd{cli-prompt, &lt;string&gt;}
573  * Configure the CLI prompt to be @c string.
574  *
575  * @cfgcmd{cli-history-limit, &lt;nn&gt;}
576  * Limit commmand history to @c nn lines. A value of @c 0
577  * disables command history. Default value: @c 50
578  *
579  * @cfgcmd{cli-no-banner}
580  * Disable the login banner on stdin and Telnet connections.
581  *
582  * @cfgcmd{cli-no-pager}
