Access Control Lists. This is a set of "rules" to let access or not to a
file. They are often considered better than simple Unix permission (where
each file has a owner and group, and read/write/execute for owner, group
and "world"), because you can have this file that is owned by "pp", group
"users", permissions (Unix-style) rw-r--r--, but you'd like to let user
"bdc" to write to it. With ACL there is no group to create (a separate
group with "pp" and "bdc" and changing the permission to rw-rw-r--), you
just invoke a command that let user "bdc" get special rw- permissions
instead of the r-- he would normally have.
