ncidef2pasm - generate PIR?

[Tim Bunce]

In runtime/parrot/library/ I see

        ncurses.declarations
        ncurses.pasm
        ncurses.pbc
        ncurses.pir

and I see tools/utils/ncidef2pasm.pl that'll convert
ncurses.declarations into ncurses.pasm.

But where did ncurses.pir come from? (Originally ncurses.imc?)

ncidef2pasm.pl can't generate pir, though I see that being suggested
by chromatic in http://www.nntp.perl.org/group/perl.perl6.internals/21353

Was it written by hand, or is there some utility I'm missing?

Tim.
