+  The \code{sort} command is a variant of \code{search} with sorting semantics for
+  the results.  Returned data contains a space
+  separated list of matching message numbers.
+
+  Sort has two arguments before the \var{search_criterium}
+  argument(s); a parenthesized list of \var{sort_criteria}, and the searching \var{charset}.
+  Note that unlike \code{search}, the searching \var{charset} argument is mandatory.
+  There is also a \code{uid sort} command which corresponds to \code{sort} the way
+  that \code{uid search} corresponds to \code{search}.
+  The \code{sort} command first searches the mailbox for messages that
+  match the given searching criteria using the charset argument for
+  the interpretation of strings in the searching criteria.  It then
+  returns the numbers of matching messages.
+
+  This is an \samp{IMAP4rev1} extension command.
