I'm looking for the documentation for SpatiaLite functions but all my links are failing.
The Gaia GIS website appears to be down https://www.isitdownrightnow.com/gaia-gis.it.html, but I'm not sure if this is a temporary problem, or whether the docs have been moved somewhere else.
I have found some docs on the Wayback Machine, but this also suggests that some pages, at least, are no longer maintained. http://web.archive.org/web/20200503035740/http://www.gaia-gis.it/gaia-sins/spatialite-cookbook/html/new-geom.html
Is there a current repository for the SpatiaLite Manual and documentation?
