hl-gmail-bulk
hl-gmail-bulk is a personal tool used by one person: the owner of the Gmail account it connects to.
It finds messages that match a search the owner chooses, then archives them, marks them as read, or adds or removes the owner's own labels. It can undo its own changes. It never sends, drafts, forwards, trashes or deletes mail, and it does not read message subjects, senders, bodies or attachments.
