FYI, it's good practice to put spaces around operators as it makes for more readable code. e.g.

```php
echo('Updating Pivotal label for story(' . $pivStoryId . ': ' . $labelName . ')' . "\n");
```
If you don't like it making the line more bulky it's better to either stick the variables in the string without the concatenation operators or use [sprintf](http://us2.php.net/sprintf). Code readability is key.
