- To: Automake <automake at gnu dot org>
- Subject: 83-lang-name.patch
- From: Akim Demaille <akim at epita dot fr>
- Date: Sun, 25 Mar 2001 17:55:02 +0200
- List-Id: Discussion list for automake <automake.gnu.org>
Index: ChangeLog
from Akim Demaille <akim@epita.fr>
* automake.in (Language): Add attribute `name.
(®ister_language): The name of the language is now given in the
hash.
No longer use `$lang' as the name of the language.
Rename `$lang_obj' as `$lang'.
