Add group descriptions to groups in profiles

If for example a profile is being used to allow users to signup for your many email newsletters you are going to want a description next to the name for each newsletter. I had to do this in a really hack way:

function oa_custom_civicrm_buildForm($form_id, &$form) {
switch ($form_id) {
case 'CRM_Profile_Form_Dynamic':
foreach($form->_elements as &$element) {

// Add the group descriptions to the newletter form elements.
if ($element->_name == 'group') {
db_set_active('civicrm');
foreach($element->_elements as &$option) {
if ($description = db_result(db_query('SELECT description FROM civicrm_group WHERE id = %d', $option->_attributes['name'])))

{ $option->_text .= '<div style="font-weight:normal">'. $description .'</div>'; }

}
db_set_active();
}

}
break;
}
}
