package require Tcl 8.4
package require critcl
# @sak notprovided PACKAGE
package provide    PACKAGE 1

# Note: The implementation of the PARAM virtual machine
#       underlying the C/PARAM code used below is inlined
#       into the generated parser, allowing for direct access
#       and manipulation of the RDE state, instead of having
#       to dispatch through the Tcl interpreter.

    ## RDE runtime, inlined, and made static.

    # This is the C code for the RDE, i.e. the implementation
    # of pt::rde. Only the low-level engine is imported, the
    # Tcl interface layer is ignored.  This generated parser
    # provides its own layer for that.
