 Sharing a locally modified clone then works as follows, using your
 user name instead of "wenzelm":
 
-  hg out ssh://wenzelm@lxbroy10//home/isabelle-repository/repos/isabelle
+  hg out ssh://[e-mail]//home/isabelle-repository/repos/isabelle
 
 In fact, the "out" or "outgoing" command performs only a dry run: it
 displays the changesets that would get published.  An actual "push",
 with a lasting effect on the Isabelle repository, works like this:
 
-  hg push ssh://wenzelm@lxbroy10//home/isabelle-repository/repos/isabelle
+  hg push ssh://[e-mail]//home/isabelle-repository/repos/isabelle
 
 
 Default paths for push and pull can be configured in
 isabelle/.hg/hgrc, for example:
 
   [paths]
-  default = ssh://wenzelm@lxbroy10//home/isabelle-repository/repos/isabelle
+  default = ssh://[e-mail]//home/isabelle-repository/repos/isabelle
 
 Now "hg pull" or "hg push" will use that shared file space, unless a
 different URL is specified explicitly.
