 @code{enable-local-variables} into account (@pxref{Auto Major Mode}).
+This function works by walking the alist stored in
address@hidden, and applies each local variable in
+turn.  It calls @code{before-hack-local-variables-hook} and
address@hidden before and after applying the
+variables, respectively.

 the local variables list specifies a mode and @code{nil} otherwise.
 It does not set the mode nor any other file local variable.

address@hidden file-local-variables-alist
+This buffer-local variable holds the alist of file-local variable
+settings.  Each element of the alist is of the form
address@hidden@code{(@var{var} . @var{value})}}, where @var{var} is a symbol of
+the local variable and @var{value} is its value.  When Emacs visits a
+file, it first collects all the file-local variables into this alist,

   If a file local variable could specify a function that would
 be called later, or an expression that would be executed later, simply
 visiting a file could take over your Emacs.  Emacs takes several
