 The variable @code{directory-abbrev-alist} contains an alist of
 abbreviations to use for file directories.  Each element has the form
 @code{(@var{from} . @var{to})}, and says to replace @var{from} with
address@hidden when it appears in a directory name.  The @var{from} string is
-actually a regular expression; it is matched against directory names
-anchored at the first character, so it should start with @samp{\`}, to
-support directory names with embedded newlines (which will defeat
address@hidden).  The @var{to} string should be an ordinary absolute
-directory name.  Do not use @samp{~} to stand for a home directory in
-that string.  The function @code{abbreviate-file-name} performs these

 You can set this variable in @file{site-init.el} to describe the
 abbreviations appropriate for your site.
