[Xotcl] replacing libtcl

Hi,

I have an application (TORQUE resource manager) which provides a TCL interface to its C library and provides the ability to program its behaviour using TCL. Basically it has a C program (pbs_sched) which calls Tcl_CreateInterp() and other Tcl library calls, and then runs a TCL script which I can write to control its behaviour.

I would like to include XOTcl functionality to my control script, but naively using "package require XOTcl" doesn't seem to work. I get "TCL error @ line 3: can't find package XOTcl". Which I guess indicates you can't do that from a standard TCL script.

So, is there a simple way to drop the XOTcl interpretor in place of the normal Tcl interpretor? Or just to add XOTcl functionality?

Thanks,

Kevin
