This task describes how to customize content
  transformations.
    - 
        Copy the following file:
        <configRoot>/alfresco/content-services-context.xml 
- Paste this file into the <extension> directory or in your preferred directory.
- 
        Open the file. Transformers start below the comment:
        <!-- Content Transformations --> 
- Locate the bean containing a transformer that is most similar to the transformer that you want to add. (It is unlikely that you would want to modify an existing transformer.)
- Delete every pair of <bean> </bean> tags except the pair containing the similar transformer.
- Rename and modify the bean.
- 
        Save the file with a meaningful name.
        Note:If you save the file in the <extension> directory, the filename must end with ‑context.xml.
