+* The longest pattern which matches an input string is always chosen.
+* For equal-length patterns, the first occurring in the rules list is chosen.
+* INITIAL is the starting condition, to which all non-conditional rules apply.
+* When in an exclusive condition, only those rules defined for that condition apply.
+*
+* Exclusive states change parsing rules while the state is active.
+* There are exclusive states for quoted strings, extended comments,
+* and to eliminate parsing troubles for numeric strings.
+* Exclusive states:
+* <xc> extended C-style comments - tgl 1997-07-12
+* <xq> quoted strings - tgl 1997-07-30
+* <xm> numeric strings with embedded minus sign - tgl 1997-09-05
+* <xd> delimited identifiers (double-quoted identifiers) - tgl 1997-10-27
+*
+* The "extended comment" syntax closely resembles allowable operator syntax.
+* So, when in condition <xc>, only strings which would terminate the
+* "extended comment" trigger any action other than "ignore".
+* Be sure to match _any_ candidate comment, including those with appended
+* operator-like symbols. - thomas 1997-07-14
