+This function arranges to evaluate @var{form} at the end of loading
+the file @var{library}, each time @var{library} is loaded. If
@var{library} is already loaded, it evaluates @var{form} right away.
+Don't forget to quote @var{form}!
-If @var{library} is a string, it must exactly match the argument of
address@hidden used to load the library. To get the proper results when an
-installed library is found by searching @code{load-path}, you should not
-include any directory names in @var{library}.
+You don't need to give a directory or extension in the file name
address@hidden you just give a bare file name, like this:
+
address@hidden
+(eval-after-load "edebug" '(def-edebug-spec c-point t))
address@hidden example
+
+To restrict which files can trigger the evaluation, include a
+directory or an extension or both in @var{library}. Only a file whose
+absolute true name (i.e., the name with all symbolic links chased out)
+matches all the given name components will match. In the following
+example, @file{my_inst.elc} or @file{my_inst.elc.gz} in some directory
address@hidden/foo/bar} will trigger the evaluation, but not
address@hidden:
+
address@hidden
+(eval-after-load "foo/bar/my_inst.elc" @dots{})

@var{library} can also be a feature (i.e.@: a symbol), in which case
@var{form} is evaluated when @code{(provide @var{library})} is called.
