[Rivet] Installation of Rivet in my home

[Eike von Seggern]

Hi Flavia,

if the suggestion Andy made is not working for you, you can try to
replace lines 17--19 with

unichr2entity = {}
for code, name in codepoint2name.iteritems():
    # exclude "&"
    if code != 38:
        unichr2entity[unichr(code)] = u"&%s;" % (name)

This should work, no matter which version of Python your using.

Cheers,
    eike
