The checkout subcommand replaces the symlink that normally points at a
|
|
|
|
|
file's content, with a copy of the file. Once you've checked a file out,
|
|
|
|
|
you can edit it, and `git commit` it. On commit, git-annex will detect
|
|
|
|
|
if the file has been changed, and if it has, `add` its content to the
|
|
|
|
|
annex.
