[Zope] New restricted python - How to use in my Product?

Hi. In one of my products i use following code: import rexec r_env = rexec.RExec() selected=r_env.r_eval(self.default) that was zope 2.3 and python 2.0. With Zope 2.4.0 there is the new RestrictedPython module with this "expression" thing, but I can't find any useful documentation on how to use that. regards Christian -- Christian Theune - ct@gocept.com gocept gmbh & co.kg - schalaunische strasse 6 - 06366 koethen/anhalt tel.+49 3496 3099112 - fax.+49 3496 3099118 mob. - 0178 48 33 981 reduce(lambda x,y:x+y,[chr(ord(x)^42) for x in 'zS^BED\nX_FOY\x0b'])
