+ * Thermals are normal lines on the layout. The only thing unique
+ * about them is that they have the USETHERMALFLAG set so that they
+ * can be identified as thermals. It is handy for pcb to automatically
+ * make adjustments to the thermals when the user performs certain
+ * operations, and the functions in thermal.h help implement that.
