getting listing/information for 'colloc'

[Dushan Mitrovich]

How do I get a listing for the function 'colloc' so I can understand
what its arguments and results mean?  I've looked in the manual and on
the Internet and only found versions of an example that's too cryptic
to be of help.

I posted a similar question a few weeks ago but got no response.  Does
anyone have any information about this?

Thanks.
