+## @deftypefn {Function File} {} regexptranslate (@var{op}, @var{s})
+## Translate a string for use in a regular expression. This might
+## include either wildcard replacement or special character escaping.
+## The behavior can be controlled by the @var{op} that can have the
+## values
+##
+## @table @asis
+## @item "wildcard"
+## The wildcard characters @code{.}, @code{*} and @code{?} are replaced
+## with wildcards that are appropriate for a regular expression.
+##
+## @item "escape"
+## The characters @code{$.?[]}, that have special meaning for regular
+## expressions are escaped so that they are treated literally.
