pyFreenet3 0.6.0 updates the spawn source (it can now spawn an on-demand Hyphanet node version 1497) and freesitemgr no longer fails with a missing index.html
aside: #Hyphanet is the original #Freenet 🐇,
a peer-to-peer platform for
censorship-resistant and privacy-respecting
publishing and communication,
in development since 1999.
