From 1b81d8cb19d8da6d865b7fca5a095dd5fec8d209 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 20 May 2018 20:40:02 +0200 Subject: help: use command-list.txt for the source of guides MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The help command currently hard codes the list of guides and their summary in C. Let's move this list to command-list.txt. This lets us extract summary lines from Documentation/git*.txt. This also potentially lets us list guides in git.txt, but I'll leave that for now.
