From: Junio C Hamano Date: Sun, 25 Nov 2007 07:48:04 +0000 (-0800) Subject: Start preparing the API documents. X-Git-Tag: v1.5.4-rc1~49 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=530e741;p=git.git Start preparing the API documents. Most of them are still stubs, but the procedure to build the HTML documentation, maintaining the index and installing the end product are there. I placed names of people who are likely to know the most about the topic in the stub files, so that volunteers will know whom to ask questions as needed.
