RE: how to arrange source control?

(back on the list so others can correct what I said)

So, if you make libraries submodules within an app, does git make a

new

copy of the library source
and put it under the app, or does it just store a different kind of
object representing the current
state of the library source under the app?

It looks like copies of the source.  Obviously they are, if the versions
differ!  But git supposedly does some hard linking under the hood, so it
doesn't waste disk space.  I don't know if that applies to the working
directory files too, or just to the internal repository implementation
files.

Is there a way to later automatically merge library changes done in
different apps?

No, it's like any other change.  That library will have its own git repo
in that subdirectory.  You need to check out a branch, change it, then
push.  The other apps, even on the same machine, will not use the new
stuff until you tell it to.  That's a feature -- it will keep pinned to
what it was building against until you are ready to upgrade.

I've not taken it to its logical conclusion of libs that use other

libs

which are also used directly by the app.

Yes, some of my libs use other libs, all of which are used by certain
apps.

I've never used version control before. I always made a 'snapshot' of
code a a milestone, but I'm hoping
there is a better way.

Another way I thought about, that might be just the ticket for you, is
to make all the apps and libs in your current directory structure into
submodules of a single master suite repository, which doesn't have
anything in it other than those submodules.
