phpGroupWare attempts to provide developers with a useful API to handle common tasks.
To do this we have created a multi-dimensional class $phpgw->.
This allows for terrific code organization, and help developers easily identify the file that the function is in. All the files that are part of this class are in the inc/core directory and are named to match the sub-class.
Example:$phpgw->send->msg() is in the inc/phpgwapi/phpgw_send.inc.php file.
