MarsSeed [1] filed a deletion request for mcabber-module-disco-hg [2]: Orphaned VCS package for a module for the old version of mcabber chat client. Source and upstream URL gone (404). From web search I've found a mirror repository where it can be seen the development has been abandoned in 2014: http://hg.lilotux.net/mod-mcabber-disco/ I think it's better to delete this abandoned package as it's not been maintained for the last 5 years, it seems it is not needed by users anymore.
