Is it possible to use sys.ini language file for Joomla v1.5 plugin? I want to use it during plugin install. Because default language ini file is not accessible during installation process. So install manager outputs only language key constants like PLG_MY_PLUGIN_DESCRIPTION. I haven't found any hint about it in Joomla v1.5 developer manuals. So I guess sys.ini files work only with components?
Your help would be appreciated.
