With respect to a computer filesystem, an access control
list (ACL) is a list of permissions attached to an object.
The list specifies who or what is allowed to access the
object and what operations are allowed to be performed on
the object. In a typical ACL, each entry in the list
specifies a subject and an operation: for example, the
entry (Alice, delete) on the ACL for file WXY gives Alice
permission to delete file WXY.
