Invoking a workflow (*.ipm) through a custom menu item

System

Hi All,

**************************
* TeamSite 6.7.1 SP1
* Solaris 9
* Workflow Modeler 1.0.0.1
*************************

We are currently trying to invoke a workflow using Workflow Modeler (v1.0.0.1) through a custom menu item within TeamSite. Is there something equivalent to iwwft_instantiator.cgi? If someone has done this or can point me to some documentation, I would greatly appreciate it.

Thanks,
James
