[TxMt] Customizing Default Bundles

[Ken Scott]

I'm helping a group that I consult with in customizing TextMate for  
their PHP development.

They have a library of functions within their company that they want  
to have syntax-highlighted, similar to the built-in PHP functions.

I accomplished this by creating a custom bundle, making a scope for  
their functions and adding the appropriate functions to the patterns  
section of the new language file.

My problem is this: In order to get this new scope included with PHP  
files, I modified the default PHP.tmbundle with
  		{	include = 'source.php.ccb'; },

This works great, everything highlights. *But*, now this is a custom  
PHP bundle, and any updates to the default will be masked, until the  
new default is manually changed.

Is there any way that I can "inject" my new scope into the PHP bundle  
without modifying the PHP bundle itself? I tried adding another  
language to my custom bundle, and just putting the include line in  
for the source.php scope. This disabled all the other PHP functionality.

Thanks for the help,
Ken Scott
