/**
 * @defgroup VocabularyResources	Vocabulary resources in SCI
 *
 * vocab.999 / 999.voc (unneeded) contains names of the kernel functions which
 * are implemented by the interpreter. In Sierra SCI, they are used exclusively
 * by the debugger, which is why keeping the file up to date was less important.
 * This resource is notoriously unreliable, and should not be used. Fortunately,
 * kernel names are the same in major SCI revisions, which is why we have them
 * hardcoded.
 *
 * vocab.998 / 998.voc (unneeded) contains opcode names. Opcodes have remained
 * the same from SCI0 to SCI2.1, and have changed in SCI3, so this is only used
 * on demand for debugging purposes, for showing the opcode names
 *
 * vocab.997 / 997.voc (usually needed) contains the names of every selector in
 * the class hierarchy. Each method and property '''name''' consumes one id, but
 * if a name is shared between classes, one id will do. Some demos do not contain
 * a selector vocabulary, but the selectors used by the engine have stayed more or
 * less static, so we add the selectors we need inside static_selectors.cpp
 * The SCI engine loads vocab.997 on startup, and fills in an internal structure
 * that allows interpreter code to access these selectors via #defined macros. It
 * does not use the file after this initial stage.
 *
 * vocab.996 / 996.voc (required) contains the classes which are used in each
 * script, and is required by the segment manager
 *
 * vocab.995 / 995.voc (unneeded) contains strings for the embedded SCI debugger
 *
 * vocab.994 / 994.voc (unneeded) contains offsets into certain classes of certain
 * properties. This enables the interpreter to update these properties in O(1) time,
 * which was important in the era when SCI was initially conceived. In SCI, we
 * figured out what '''property''' a certain offset refers to (which requires one to
 * guess what class a pointer points to) and then simply use the property name and
 * vocab.997. This results in much more readable code. Thus, this vocabulary isn't
 * used at all.
 *
 * SCI0 parser vocabularies:
 * - vocab.901 / 901.voc - suffix vocabulary
 * - vocab.900 / 900.voc - parse tree branches
 * - vocab.0 / 0.voc - main vocabulary, containing words and their attributes
 *                     (e.g. "onto" - "position")
 *
 * SCI01 parser vocabularies:
 * - vocab.902 / 902.voc - suffix vocabulary
 * - vocab.901 / 901.voc - parse tree branches
 * - vocab.900 / 900.voc - main vocabulary, containing words and their attributes
 *                        (e.g. "onto" - "position")
