Stanzas are applied in order: For each category (u = user,

set (+), clear (-), or copy (=), r = read, w = write, x = execute.
- s = u+s = suid, g+s = sgid, o+s = sticky. (+t is an alias for o+s).
+ s = u+s = suid, g+s = sgid, +t = sticky. (o+s ignored so a+s doesn't set +t)

sticky: can't delete files you don't own out of this directory
X = x for directories or if any category already has x set.
