In following .gitmodules example, we can use "git submodule update service" to update all sub-submodules of submodule "service" (util, imsearch, imcrawler). We don't have to do "git init" first. Without the multiple level module definition, "git init" is good idea, since every time we want to 'git update', we needn't give so many module paths. However, if we introduce multiple level module definition, we can define the module groups we are interested such as crawler, search and the toppest group service. So we just need to type one or few module names which makes "git init" not so useful. And it's more flexible by using module name: at one time we can update "cralwer" module group, and at another time we can update "search" module group. .gitmodules example ------------------------------------------------------ [submodule "service"] submodule = crawler submodule = search [submodule "crawler"] submodule = util submodule = imcrawter [submodule "search"] submodule = util submodule = imsearch [submodule "util"] (1) url = git://xyzzy/util.git [submodule "imsearch"] path = search/imsearch url = git://xyzzy/imsearch.git [submodule "imcrawler"] path = crawler/imcrawter url = git://xyzzy/imcrawter.git ------------------------------------------------------ > -- > lh > -- Ping Yin -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
