t = Translation(entry_point[,<options>]) t.annotate([<options>]) t.rtype([<options>]) t.backendopt[_<backend>]([<options>]) t.source[_<backend>]([<options>]) f = t.compile[_<backend>]([<options>])

and t.view(), t.viewcg()

<backend> = c|llvm (for now) you can skip steps

<options> = argtypes (for annotation) plus
keyword args: gc=...|policy=<annpolicy> etc
