 @address@hidden line.  @code{set-auto-mode} does that, also taking
 @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.
+
 If the optional argument @var{mode-only} is address@hidden, then all
 this function does is return @code{t} if the @address@hidden line or
 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,
+and then the @code{hack-local-variables} function applies them one by
+one.

address@hidden before-hack-local-variables-hook

address@hidden hack-local-variables-hook

   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
