| The first kind of ''repo'' is not the full command; rather, it is a simplified version called the //tool launcher//; this is the single-executable command you download initially, and make sure is part of your search path so that when you invoke ''repo'', that is the command that is located and executed. It's common to install that in your personal ''~/bin'' directory, which is almost always already part of your search path. | The first kind of ''repo'' is not the full command; rather, it is a simplified version called the //tool launcher//; this is the single-executable command you download initially, and make sure is part of your search path so that when you invoke ''repo'', that is the command that is located and executed.

| Once you start working with ''repo'' and initialize your first repository, each and every repository will, as part of being initialized, have installed within it the //full// version of ''repo'', which supports all of the subcommands. However, even as you're working with ''repo'', you always, always, always invoke the initial tool launcher which, as soon as it realizes it's being run in the context of an actual repository, will hand off control to that repo's full version. | Once you start working with ''repo'' and start initializing repositories, each and every repository will, as part of being initialized, have installed within it the //full// version of ''repo'', which supports all of the subcommands.

| In other words, even though every single ''repo'' repository you initialize gets its own copy of the full version of the command, you should never run that full version directly -- you always invoke the simpler, tool launcher version, which will take it from there. | In other words, even though every single ''repo'' repository you initialize gets its own copy of the full version of the command, you should never run that full version directly -- you always invoke the simpler, tool launcher version, which will take it from there. |

| Note well that this is not the ''repo'' command itself; rather, it is the //launcher tool// that will, every time you initialize a new repo directory, copy the //actual// ''repo'' command into that new directory. | Once again, this is not the full version of the command; its job is to simply initialize new repositories when you run ''repo init'', then in each of those repositories install the //full// version of the command, which will be used from then on. |
