		If this option is selected, the NSH will call into platform-specific
		logic in order to get the MOTD.  The function prototype for this
		call is:

			void platform_motd(FAR char *buffer, size_t buflen);

		Where buffer is the location to return the MOTD and buflen is the
		length of that buffer.  The maximum size of the buffer is determined
		by NSH_FILEIOSIZE.  An appropriate location for the
		implementation of platform_motd would be within apps/platform/<board>.

		One newline will be inserted after the platform-supplied message.

		platform_motd() is prototyped and described in apps/include/nshlib/nshlib.h

		Select this option only if (1) you don't mind a modest increase
		in the FLASH footprint, and (2) you work with a terminal that
		supports extensive VT100 editing commands.

	---help---
		If selected, then the output from commands, from file applications, and
		from NSH built-in commands can be used as arguments to other
		commands.  The entity to be executed is identified by enclosing the
		command line in back quotes.  For example,

			set FOO `myprogram $BAR`

		Will execute the program named myprogram passing it the value of the
		environment variable BAR.  The value of the environment variable FOO
		is then set output of myprogram on stdout.

		Because this feature commits significant resources, it is disabled by

		Support concatenation of strings with environment variables or command
		output.  For example:

			set FOO XYZ
			set BAR 123
			set FOOBAR ABC_${FOO}_${BAR}

		would set the environment variable FOO to XYZ, BAR to 123 and FOOBAR
		to ABC_XYZ_123.  If NSH_ARGCAT is not selected, then a slightly small
		FLASH footprint results but then also only simple environment
		variables like $FOO can be used on the command line.

config NSH_NESTDEPTH

		The maximum number of nested if-then[-else]-fi sequences that
		are permissible.  Default: 3

config NSH_DISABLEBG

	default y if DEFAULT_SMALL
	default n if !DEFAULT_SMALL

		This can be set to 'y' to suppress support for background

		execution is not.

		PL2303 and PL2303_CONSOLE - Set up the Prolifics PL2303

		CDCACM and CDCACM_CONSOLE - Set up the CDC/ACM serial

		to support the NSH console. If CONFIG_NSH_ALTCONDEV is selected,
		then NSH_ALTSTDIN, NSH_ALTSTDOUT and NSH_ALTSTDERR must be set
		to select the serial devices used to support the NSH console.
		This may be useful, for example, to separate the NSH command
		line from the system console when the system console is used to
		provide debug output.

		Default: stdin, stderr and stdout (probably "/dev/console")

		NOTE 1: When any other device other than /dev/console is used
		for a user interface, (1) linefeeds (\n) will not be expanded to
		carriage return / linefeeds (\r\n).  You will need to set
		your terminal program to account for this.  And (2) input is
		not automatically echoed so you will have to turn local echo on.

		NOTE 2:  This option forces the console of all sessions to use
		NSH_ALTSTD(IN/OUT/ERR).  Hence, this option only makes sense for
		a system that supports only a single session.  This option is,
		in particular, incompatible with Telnet sessions because each
		Telnet session must use a different console device.
