[Tracker] Context extraction API/program

[Andrew Leung <aleung soe ucsc edu>]

Hi,

I would like to utilize Tracker's file content extraction mechanism  
within my own program. Basically I would like to be able to parse  
various file types and pull out keywords. Does Tracker have any  
mechanism (API/separate program) that can I can use to pull content  
from various file types?

Beagle search has a program called 'beagle-extract-content' that I  
have been using for this purpose though I haven't been particularly  
happy with it. Thanks a lot.

Andrew
