A list is either a +## "normal" list or a "union" list. A normal list is an "AND" list +## composed of "OR" lists, which in turn are composed of simple +## dependencies. A union list is an AND list composed of only simple +## dependencies. That is, a normal list is of the form +## \fIdep\ |\ dep,\ dep\fP, and a union list is of the form +## \fIdep,\ dep\fP.
