Force plugins order

[Olivier Nicole <on...@cs.ait.ac.th>]

Hello,

Is there a way to force the order that SA will try the various plugins?

Typically I would have:

- a first plugin that analyzes PDF attachment, pushed the text part
  back as text (post_message_parse) and the images as new message
  parts (add_body_part);

- a second plugin that does OCR of the images attachments and pushes
  the discovered text back as text (post_message_parse).

Obviously the first plugin should come first as it may discover images
that will be OCRed by the second plugin.

How to force the order of the plugins?

Best regards,

Olivier
