+
+DESCRIPTION
+
+ The generic seclet linking routine. The caller should have
+ set up seclets for all the output sections. The DATA argument
+ should point to a memory area large enough to hold the largest
+ section. This function looks through the seclets and moves
+ the contents into the output sections. If RELOCATEABLE is
+ true, the orelocation fields of the output sections must
+ already be initialized.
