This program also installs under "ekko" for unambiguous use.

	echo - output arguments separated by a delimiter

	syntax: echo [-E | -n | -F<delimiter> | -v | -c]... [--] [<arg>...]
		-c	output configured internal character-size
		-E	disable escapes completely, outputs even backslashes
		-e	(ignored for compatibility with some versions of echo)
		-Fs	use the string "s" for the delimiter, may have escapes
		-F	disable output delimiting, normally done with spaces
		-n	omits the normally-output trailing newline
		-v	output version information
		--	signals the end of option processing
	Options are not output; use the -- option or \- to allow
	the output of text with leading dashes; for example:
		echo '\-n'
		echo -- -n
	...will both actually output '-n'.
	Running echo with an unknown option, -h, or --help outputs help.

	All normal ANSI C character escape sequences are available:
		\a	ANSI/C alarm (bell)
		\b	ANSI/C backspace
		\f	ANSI/C formfeed
		\n	ANSI/C newline
		\r	ANSI/C return
		\t	ANSI/C h-tab
		\v	ANSI/C v-tab
		\ooo	ANSI/C code of three octal digits (ooo)
		\xhh	ANSI/C code of two hex digits (hh)
	(See ANSI K&R C book, section A2.5.2, page ~193, for details)
		\c	omit the final newline (duplicates the '-n' option)
		\E	disable escapes for the rest of the current arg
		\e	GNU/C escape character (\033)
	Any other character escaped by a backslash is simply output.
	Any backslashes found at the end of args will be output.
