Several people have made similar mistakes in beliving that "git submodule init" can be used for adding submodules to a working directory, whereas "git submodule add" is the command that should be used. That *is* documented at the top of the manual page for "git submodule", but my error was enhanced by a subtle error in the documentation of "init".
The text as it is written suggests that init's behavior is driven by the contents of .submodules. But in fact, its behavior is driven by the existing gitlinks in the file tree, possibly limited by the <path> arguments. (Which is *why* "git submodule init" can't *add* submodules; it only processes *existing* submodules.) I would like to suggest that the manual page be updated to remove the error in the description of the init subcommand, along with another addition to tell the submodule logical name that is used by the "add" subcommand: --- man1 2013-04-26 12:02:16.752702146 -0400 +++ man3 2013-05-02 21:06:00.020353100 -0400 @@ -61,6 +61,8 @@ to exist in the superproject.
