According to http://orgmode.org/elpa.html the org-plus-contrib package has all the files in the /contrib directory but it looks like it's only grabbing the files that begin with "org-". None of the "ox-" or "ob-" are in the repo. Looks like this line in servers.mk is the culprit:
elpaplus-dirty elpaplus-up: ORG_ADD_CONTRIB=org-* Is this an oversight or by design? Thanks.
