@ -1933,10 +1933,13 @@ 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
@var{to} when it appears in a directory name. The @var{from} string is
actually a regular expression; it should always start with @samp{\`}.
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 substitutions.
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
@samp{^}). 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
substitutions.
You can set this variable in @file{site-init.el} to describe the
abbreviations appropriate for your site.
