+...@deffn Command date [[year-]month-day] [hour:minute[:second]]
+With no arguments, print the current date and time.
+
+Otherwise, take the current date and time, change any elements specified as
+arguments, and set the result as the new date and time. For example, `date
+01-01' will set the current month and day to January 1, but leave the year,
+hour, minute, and second unchanged.

+...@deffn Command echo [...@option{-n}] [...@option{-e}] string @dots{}
+Display the requested text and, unless the @option{-n} option is used, a
+trailing new line. If there is more than one string, they are separated by
+spaces in the output. As usual in GRUB commands, variables may be
+substituted using @sam...@{var@}}.
+
+The @option{-e} option enables interpretation of backslash escapes. The
+following sequences are recognised:
+
+...@table @code
+...@item \\
+backslash
+
+...@item \a
+alert (BEL)
+
+...@item \c
+suppress trailing new line

+...@item \n
+new line
+
+...@item \r
+carriage return
+
+...@item \t
+horizontal tab
+
+...@item \v
+vertical tab
+...@end table
+
+When interpreting backslash escapes, backslash followed by any other
+character will print that character.
