Most users use only the first function.
The AFS function is admittedly clunky and quirky and is not recommended unless you know a little bit about using AFS in UNIX, which you will probably need to know when setting permissions. The MacStanford web link on the left lets you download the latest copy of MacLeland as well as the other programs in MacStanford to your Macintosh for installation. This version of MacLeland Help accompanies MacLeland 1.4, published February 2000. MacLeland is a product of Stanford University. Please see the list of contributors to this program in the About MacLeland command.
