=================
Ok, so you're a CVS user. That's ok, it's a treatable condition, and the
already.
The thing about CVS is that it absolutely sucks as a source control

One particular suckage of CVS is very hard to work around: CVS is

+things like making branches of just a subset of the project. git can't
track that, since git never tracks things on the level of an individual
file, only on the whole project level.
The good news is that most people don't do that, and in fact most sane
people think it's a bug in CVS that makes it tag (and check in changes)
one file at a time. So most projects you'll ever see will use CVS

Second: CVS has the notion of a "repository" as opposed to the thing
that you're actually working in (your working directory, or your

people can synchronize with. See details later, but in the meantime
just keep in mind that with git, every checked out working tree will

the equivalent of the above command, and can be used like this:
