egroupware_official/phpgwapi/inc/class.config.inc.php
Ralf Becker c85d34c0fe changed the following table-names:
- phpgw_accounts --> egw_accounts
- phpgw_acl --> egw_acl
- phpgw_log(_msg) --> egw_log(_msg)
- phpgw_config --> egw_config
- phpgw_applications --> egw_applications
This requires code-changes in many apps. Quite often I was able to replace the db access, with calls to the appropreate classes.
