+/**
+  * TERMINOLOGY
+  *
+  * A multiplexer tree (mux tree) is a tree composed exclusively of muxes.
+  * By mux, I mean $mux or $pmux. By port, I usually mean input port.
+  * The children of a node are all the muxes driving its input ports (A, B).
+  * It must be rooted in a "root mux", a mux which has multiple mux users
+  * or any number of non-mux users. Only the root and leaf nodes can be
+  * root muxes, not the internal nodes. Leaf nodes that are root muxes
+  * are roots of "input trees".
+  *
+  * OPERATING PRINCIPLE
+  *
+  * This pass traverses mux trees, learning port activations and making
+  * assumptions about them as it goes. When valid, ports are replaced
+  * with constants, or removed if they can never be activated.
+  * When valid, muxes are replaced with shorts from port to output,
+  * or removed if their outputs are found to be no longer observable.
+  *
+  * Input trees can be recursed into if limits_t::recursions_left allows.
+  * Otherwise, the input tree is queued for a re-run with a fresh knowledge_t.
+  * At any point, if glob_evals_left goes to 0, the pass terminates.
+  *
+  * Unlike share, this pass doesn't use SAT to learn things about logic
+  * driving the mux control signals, and traverses mux regions from users
+  * to drivers.
