  - VTK API Available in vovtasker
    The binary vovtasker has access to only a limited VTK API. This is because the protocol between vovtasker and vovserver has special requirements. This limited API is used, for example, in the taskerLSF.tcl file, in taskerRes.tcl, and in general in all Tcl scripts read by vovtasker.
