Summary
We have some dead links (and lost content) from Platform documentation, see https://github.com/eclipse-platform/eclipse.platform.ui/issues/3391 mentioning a dead link to https://www.eclipse.org/community/rcpcp.php . The page is still visible from Internet Archive in early February 2024.
Was the content removed? Or is it just PHP now always returning 404? Was the content migrated automatically to static HTML or markdown and made available somewhere else? If not, is it still possible to get the content of this page and link (and maybe even the whole community/ folder) so we could include it in Platform documentation directly?
