<oerjan> le/rn hoag/`[hd]o[aw][gt] [<filename>] is a set of commands for querying HackEgo logs. `hoag is the basic version. d adds dates, w looks only in wisdom, and t lists in reverse.

`revert is a bit buggy. The canary.orig error message is annoying but seemingly harmless. However, reverting a newly created file tends not to work - use `rm instead.
