-<p>A keyboard mapping DLL provides a set of lookup tables that the generic <filepath>ektran.dll</filepath> uses
-to convert scancodes to keycodes. A keyboard mapping DLL is implemented in
-a base port. </p>
-<p>The basic purpose of the tables is to provide a mapping from scancodes
-to keycodes, so that, given a scancode, the corresponding keycode can be found.
-The tables are organised so that there is, in effect, one set of lookup tables
-for each likely combination of modifier key states. <filepath>ektran.dll</filepath> compares
-the modifier keys that have been pressed with the stored modifier key state
-combinations to decide which set of lookup tables to use. </p>
-<p>An outline set of tables is provided in the template port. The ports for
-the H4 reference board provide useful examples of how the tables can be constructed. </p>
-<p>The following list outlines the structure of the tables. </p>
