 Unless you specify a different name to use, @tramp{} will use the current
 local user name as the remote user name to log in with. If you need to
 log in as a different user, you can specify the user name as part of the
 filename.
 
-To log in to the remote machine as a specific user, you use the syntax
-@file{/[<user>@@<machine>]/path/to.file}.  That means that connecting to
-@code{melancholia} as @code{daniel} and editing @file{.emacs} in your
-home directory you would specify @file{/[daniel@@melancholia].emacs}.
+On Emacs, to log in to the remote machine as a specific user, you use

 The syntax of multi-hop file names is necessarily slightly different
 than the syntax of other @tramp{} file names.  Here's an example multi-hop
-file name:
+file name, first in Emacs syntax and then in XEmacs syntax:
 
+@file{/multi:rsh:out@@gate:telnet:kai@@real.host:/path/to.file}
 @file{/[multi/rsh:out@@gate/telnet:kai@@real.host]/path/to.file}
 
 This is quite a mouthful.  So let's go through it step by step.  The
-file name consists of three parts, separated by slashes and square
-brackets.  The first part is @file{/[multi}, the method specification.
-The second part is @file{rsh:out@@gate/telnet:kai@@real.host} and
-specifies the hops.  (Yes, the second part may contain even more
-slashes, so that's why this file name has more than two colons in it.)
-The final part is @file{/path/to.file} and specifies the file name on
-the remote host.

+@item The @tramp{} filename syntax differs between Emacs and XEmacs.
+
+The Emacs maintainers wish to use a unified filename syntax for
+Ange-FTP and @tramp{} so that users don't have to learn a new
+syntax.  It is sufficient to learn some extensions to the old syntax.
+
+For the XEmacs maintainers, the problems caused from using a unified
