→Luatex hosts python
}
Following [http://labix.org/lunatic-python] I was able, in a linux box, to modify luatex-snapshot-20070820.tar.bz2 so that <tt>luatex --luaonly</tt> can host python. Of course <tt>\directlua0{....}</tt> also works.
'''WARNING: these modifications break security and portability'''

print ('#1 no match')
