This is an experimental copy for testing Poikilos' issue mirroring system. Note that Gitea's migration tool can import issues, but the "Issues" checkbox is disabled when "This repository will be a mirror" is enabled (it is for this repo).
You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.
