* $Id$
*
* This parser is used in static deployment of CIAO components. This
* parser parses a deployment plan and generates a header file plan.h
* containing information about the home and servant creation
* function entry points. This can be used by a Static_NodeManager to
* instantiate instances of homes and servants just like the regular
* NodeManager. For more details, see
* $CIAO_ROOT/DAnCE/StaticConfigurator/docs/static_dance.html
