PHPDocumentor Error "nothing parsed" by parsing module file

Hi All!
wrote a module for Drupal and want to generate the documentation with phpdoc. The problem is, i get Error "nothing parsed", because my file has extension *.module and the phpdocumentor means it isnt a php file. If i rename it to *.php then is OK.

Questions:

How can i get phpdoc to parse *.module files?
Maybe exists some ini where i can extends parseractivity?

Thx for responce
