130 * 3) the type of operator used to define its sources (qv. parse.c)
131 * 4) whether it is involved in this invocation of make
132 * 5) whether the target has been remade
133 * 6) whether any of its children has been remade
134 * 7) the number of its children that are, as yet, unmade
135 * 8) its modification time
136 * 9) the modification time of its youngest child (qv. make.c)
137 * 10) a list of nodes for which this is a source (parents)
138 * 11) a list of nodes on which this depends (children)
139 * 12) a list of nodes that depend on this, as gleaned from the
140 * transformation rules (iParents)
141 * 13) a list of ancestor nodes, which includes parents, iParents,
142 * and recursive parents of parents
143 * 14) a list of nodes of the same name created by the :: operator
144 * 15) a list of nodes that must be made (if they're made) before
145 * this node can be, but that do not enter into the datedness of
146 * this node.
147 * 16) a list of nodes that must be made (if they're made) before
148 * this node or any child of this node can be, but that do not
149 * enter into the datedness of this node.
150 * 17) a list of nodes that must be made (if they're made) after
151 * this node is, but that do not depend on this node, in the
152 * normal sense.
153 * 18) a Lst of ``local'' variables that are specific to this target
154 * and this target only (qv. var.c [$@ $< $?, etc.])
155 * 19) a Lst of strings that are commands to be given to a shell
156 * to create this target.
