OK, that seems to work, in so far as the contents of the text/x-matlab
files is now indexed.   However, they seem to be indexed into the
"Other" service.  So my next question is how do I add new mime types to
the "Development" service.  Again I've noticed that in the file:
/usr/share/tracker/services/default.service
seems to contain information about how different services are indexed
and which mime-types correspond to each service.  So tried the simple
approach of adding text/x-matlab to the development section of this file
-- but this seemed to have *no* effect.  Is this to be expected?

I then tried searching through the source code (for 0.6.3) for where the
"real" mime -> service mapping is stored and found another
mime->Development service mapping in the file
src/trackerd/tracker-metadata.c
This mapping seems to be hard-coded in this file.  So is this how the
mime -> service mapping is achieved rather than through a configuration
file?  And more directly for my problem, do I just add text/x-matlab to
the development_mime_types array and re-build to add this type to the
service mapping?

Thanks again,

Jason
