+/*
+ * Keyboard Layout Microcode Definition
+ *
+ * Each time a byte is received from the keyboard it is processed through the layout microcode engine. This enables conversion from
+ * scancodes to ascii, internationalization, and various other tricky keyboard behavior.
+ * Note a "code" is defined as a single byte of data from the keyboard, a "scancode" is one or more "codes" that are sent in response to one keyboard press or release.
+ *
+ * The layout microcode can even be switched on the fly by the application to effect such changes as changing from US English to Russian layouts.
+ * They could conceivably even be loaded from disk at run-time.
+ *
+ * In the interest of efficiency there is very little error checking. Make sure your layout microcode has been debugged properly before releasing
+ * to production code.
+ *
+ * Layout microcode consists of a header followed by 1 or more records.
+ *
+ * The header consists of a KMC_HEADERSTART and associated bytes. The is used only to check it looks like it might be layout microcode and to specify the
+ * version of microcode. Future versions of layout microcode will always have the same header at least to the version number.
+ *
+ * Each record is delimited by a KMC_RECORDSTART. Each record can contain a maximum of 255 bytes.
+ * A record length of zero indicates the end of the layout microcode.
+ *
+ * A record consists a mixture of tests and actions (normally the tests are first). If a test fails the rest of this record is skipped and the next
+ * record is processed. This has the effect of AND'ing multiple tests that occur together.
+ * KMC_TEST_INIT and KMC_TEST_ERROR are special. These tests must be the first byte in their respective record as without this test being there, there
+ * is an implicit test that a code has actually been received.
+ * If no records have successful tests for this code then by extension no actions are executed. That is, the code is ignored.
+ * After fully processing a record, the next record is processed. This can be prevented by using the KMC_ACT_STOP action. When encountered all processing
+ * on this code stops.
+ *
+ * Some tests set a pseudo variable called "diff". This is then used by some actions. At the start of a new record "diff" is set to "code" (or 0 for the init and
+ * error conditions).
+ * Some tests and actions do bit operations on either the saved key-state or on the code itself. Bit numbers (which can range from 0 to 31) test or affect the
+ * "set" state of the bit. OR'ing KMC_BIT_CLEAR with the bit number test or affect the "clear" state of the bit. For example, KMC_ACT_STATEBIT with a parameter
+ * of 10 will set bit 10 of the key-state. KMC_ACT_STATEBIT with a parameter of (10 | KMC_BIT_CLEAR) will clear bit 10 of the key-state.
