MarsSeed [1] filed a deletion request for biopieces [2]: Deprecated orphan package from 2018. Upstream also doesn't maintain it since that year. [a] There are unresolved breaking issues, only a dedicated and knowledgeable packager could resolve them. [b] Last two user comments from AUR page: # @clintval commented on 2018-03-17 02:55 (CET) Does anyone use this? I don't but volunteered to maintain.... # @confusedfla commented on 2017-12-15 04:45 (CET) I don't use this anymore. Disowning.
