// to set the kLSItemQuarantineProperties attribute to a dictionary specifying

// the quarantine properties to be applied. However, it does not appear to be

|
// possible to remove an item from the quarantine directly through any public
|

|
// Launch Services calls. Instead, this method takes advantage of the fact
|
||
|
|
// that the quarantine is implemented in part by setting an extended attribute,
|
||
|
|
// "com.apple.quarantine", on affected files. Removing this attribute is
|
||
|
|
// sufficient to remove files from the quarantine.
