Hi all,

when I switch between branches, I would like like to delete some
object files and prepare some setup files.
I there a good way to do this automatically when I run "git checkout
branch", like
misusing a hook to run a make in a special directory?
All would happen in my local repository.

Thanks,
Alf

```

There is a post-checkout hook; see "git help hooks" for details.

You could also make an alias; see the documentation for "alias.*" in
"git help config".

No; for security reasons, no code (including hooks) from remote
repositories is automatically run. The usual method is to include the
hook in your repository and copy it into place after cloning.
