how did you create this models. #27 (comment) said it hard to generate models at this moment. Did you fixed #34 ?

[snozawa]

Temporarily I created this model by adding diff in rbrain/Makefile.generic.

copy-converted-irtmodels-to-euslisp-models-repository:
        -echo "(progn (defun remove-duplicates (seq &key (test #'eq) (test-not) (key #'identity)\
                                   (start 0) (end 1000000))\
   (system::raw-remove-duplicates seq test test-not key start end)) (copy-converted-irtmodels-to-euslisp-models-repository) (exit))" | $(BINDIR)/jskrbeusgl convert-model-test.l

Before reverting remove-duplicates, I was waiting for downstream package upgrade from previous Euslisp DEB-release.
jsk-ros-pkg/jsk_pr2eus#35
At this time, I'd like to fix this PR before new euslisp DEB releasing, but it takes so long time...

Is it better to revert remove-duplicate first?
#34
