From d03f39a99058c2393d7b50ac4909bdaa84b09920 Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Mon, 7 Jul 2014 15:30:12 -0500 Subject: wic: Add dummy subcommand and usage strings In order to reuse the existing subcommand infrastructure to display various general-purpose help topics, add a dummy 'help_topic' subcommand and usage string. This allows users to invoke general help topics by the natural form 'wic help ' even though topic doesn't correspond to a real subcommand.
