val tar : Fpath.t -> exclude_paths:Fpath.set -> root:Fpath.t -> mtime:int -> ( string, Bos_setup.R.msg ) Bos_setup.result
tar dir ~exclude_paths ~root ~mtime is a (us)tar archive that contains the file hierarchy
dir except the relative hierarchies present in
exclude_paths. In the archive, members of
dir are rerooted at
root and sorted according to
Fpath.compare. They have their modification time set to
mtime and their file permissions are
0o775 for directories and files executable by the user and
0o664 for other files. No other file metadata is preserved.
Note. This is a pure OCaml implementation, no
tar tool is needed.
