Using XUpdate with XIndice?

[Roger L. Costello]

Hi Folks,

The documentation says that XUpdate may be used to update the
documents in the XIndice database.  However, it provides no indication
of "how" to actually submit an XUpdate document.  Is there a
command-line command for submitting an XUpdate document?  Can someone
give me instructions on the mechanism for using XUpdate with XIndice?
