+SRFI-28 provides a basic @code{format} procedure that provides only
+the @code{~a}, @code{~s}, @code{~%}, and @code{~~} format specifiers.
+You can import this procedure by using:
+
+@lisp
+(use-modules (srfi srfi-28))
+@end lisp
+
+@deffn {Scheme Procedure} format message arg @dots{}
+Returns a formatted message, using @var{message} as the format string,
+which can contain the following format specifiers:
+
+@table @code
+@item ~a
+Insert the textual representation of the next @var{arg}, as if printed
+by @code{display}.
+
+@item ~s
+Insert the textual representation of the next @var{arg}, as if printed
+by @code{write}.
+
+@item ~%
+Insert a newline.
+
+@item ~~
+Insert a tilde.
+@end table
+
+This procedure is the same as calling @code{simple-format} (@pxref{Writing})
+with @code{#f} as the destination.
