How to download an old version of a freesite on Freenet

I just dug up that 2+ year old draft so this will be short.
Freenet-hosted websites (“freesites”) are usually advertised via a “USK@…” URI, which allows you to fetch the latest version automatically. But when a freesite is updated, actually the old one remains in the system (at least, as long as it hasn’t decayed yet). It’s possible to access any old revision (again, as long as it hasn’t been flushed) via a simple URL manipulation:

For instance, the current version of FMS is accessible via this key:
USK@0npnMrqZNKRCRoGojZV93UNHCMN-6UU3rRSAmP6jNLE,~BG-edFtdCC1cSH4O3BWdeIYa8Sw5DfyrSV-TKdO5ec,AQACAAE/fms/142/

And a specific old version would be accessed via this key:
SSK@0npnMrqZNKRCRoGojZV93UNHCMN-6UU3rRSAmP6jNLE,~BG-edFtdCC1cSH4O3BWdeIYa8Sw5DfyrSV-TKdO5ec,AQACAAE/fms-140/

The starting “USK” is replaced by “SSK”, and the end of the URI changes from [sitename]/[version]/ to [sitename]-[version]/

This used to be explained on the Freenet wiki there wiki.freenetproject.org/USK, but apparently this page was removed in the migration :/
